ling point or the matter state change PROCESS will be isothermal in nature. That is, the TEMPERATURE won't change  throughout the time of state change process. That is valid for all state evolving forms (SOLD to fluid and liquid to GAS).  In the MEAN time, Specific Heat is the measure of heat required to raise the temperature by 1 degree.  {(Tf-Ti) =1 }  C=Q/(Tf-Ti)               (Unit : Kilo Joules/Celsius)  So the Specific Heat will be equal to C=Q/(Tf-Ti)

ng metals by electrolysisMost metals need to be purified as the presence of impurities affects the properties of the metal, for example they can make impure iron brittle. The amount of different impurities which may be present in the final sample of the metal depends on what the metal is used for. Iron, for example, is rarely used in a pure form and impurities such as small amounts of carbon are important in steel, the main use of iron. Copper is a valuable metal which is widely used, particularly as an electrical conductor, unfortunately even small amounts of impurity can reduce its electrical conductivity CONSIDERABLY. To purify the metal an electrolytic process is used, with a sheet of pure copper as the negative cathode, and the impure copper as the positive anode. Copper dissolves from the anode to form copper ions, which are attracted to the cathode where they are deposited as the pure metal. Any impurities fall to the bottom of the cell forming a 'sludge', which often contains small amounts of silver and gold.Other products from ROCKS and mineralsAlthough metals form an important group of materials extracted from the ground, they are not the only useful materials. Some rocks such as limestone, sandstone and granite are used for building, and minerals such as sand, shingle and clay are used in the construction industry and for road-building. In addition to these, materials such as limestone, and rock salt are important as raw materials for the CHEMICALS industry.Rocks such as limestone and granite have been used as building materials for thousands of years. This pyramid in Egypt is mainly limestone, but the facing stone (at the top) is sandstone.Limestone - a useful rockLimestone is a sedimentary rock (see also 'Sedimentary rocks') consisting of almost pure calcium carbonate. It is an important material, with about three-quarters of the amount quarried being used in construction. Much of this is as 'aggregate' - the crushed stone used in road-building. In addition it is used as a base to neutralise acid soils, acid gases produced by burning fossil fuels, and acidified lakes produced by acid rain. It is also used in iron and glass production. It can be converted into cement, by heating with clay, and quicklime by heating to a high temperature. Quicklime, and SLAKED LIME (produced by adding water) are used to neutralise acid soils, in water treatment and in making mortarsChemicals from rock saltRock salt is chemically almost the same as the salt you may sprinkle on your food. It comes from the remains of ancient seas which have dried up and been buried under layers of rock. Most of this salt is used as a raw material for making other chemicals, particularly in the 'chlor-alkali' process. In this process, electricity is passed through a solution of sodium chloride. This converts the solution into sodium hydroxide, and releases chlorine and hydrogen as gases. These three products have important uses in their own right, as well as combining together to form bleach and hydrochloric acid.hope it helps u mate...pls. mark me brainliest

E ❤️❤️❤️ HERE IS UR ANSWER IS...DIFFERENCE BETWEEN ALTERNATING CURRENT AND DIRECT CURRENT.....LossDC transmission loss, it is not suitable for long-distance transmission,AC transmission loss is small, so suitable for long-distance transmission,UseDC voltage stability, no big noise, it is suitable for the use of electronic products. (such as televisions, radio computers, etc.)AC power to go through the rectifier/switching power supply into DC power can be used for electronic products.Measure the difference between 12V AC and DC:A) with a digital universal measurement, respectively, with 20V AC voltage and 20V DC voltage file measurement, the RESULTS will be different.B) simple measurement method: with a stylus pen (non-ordinary pen) on the wire foreskin, 12V AC will still show, 12V DC no display.Safety12V DC is safer than 12V AC. Body resistance decreased when the 12V AC still may cause the dead, 12V DC will not be in 100%.PeakAccording to the voltage pattern, 12V AC and DC instantaneous peak voltage is not the same, the instantaneous peak voltage (12V straight) ≡ 12V, instantaneous peak voltage (12V AC) = √2 × 12VConversion2V AC to 12V DC: Simple (Diode Capacitor Regulator)12V DC to 12V AC: Complex (STARTER )12) Use – most can think so (for most equipment):12V DC device 12V AC power supply (burn equipment)12V AC equipment 12V DC power supply (equipment use EFFICIENCY is reduced)HOPE THIS WILL HELP YOU ❤️ ❤️❤️STAY BLESSED ❤️ ❤️

dinal waves:-A longitudinal waves is a WAVE where the movement of the medium is in the same direction as the wave.This causes particles to move left and right inducing other particles to vibrate.The PRIMARY wave in the earthquake is the longitudinal waves.The longitudinal waves are ONE DIMENSION.TRANSVERSE waves:-Transverse waves is a wave where the movement of the medium is at a right angle to the wave direction.The particles move up and down as the wave mones horizontally.The secondary waves in a earthquake is the transverse waves.The transverse waves are the two dimension.

electric potential is constant, SAY 10 V, then there is no direction of greatest INCREASE. Hence the gradient of the electric potential is zero, and the electric field is zero EVERYWHERE INSIDE the region of constant electric potential.

t because the electric field is ZERO at a particular point, it does not necessarily mean that the electric potential is zero at that point. A good EXAMPLE is the CASE of two identical charges, separated by some distance. ... Both the electric field vectors will point in the DIRECTION of the NEGATIVE charge.

dy I think it's helpful for you buddyIn physics, motion is a change in position of an object over time. Motion is DESCRIBED in terms of displacement, distance, VELOCITY,acceleration, time, and SPEED. Motion of a BODYIS observed by ATTACHING a frame of reference to an observer and measuring the change in position of the bodyrelative to that frame.

& Explanation:Using Gold Leaf Electroscope (GLE) we can find the NATURE of charge on the body (specimen). The GLE apparatus has a disk that conducts charge while it has gold leaves that move to show the nature of charge. For example,If we bring the CHARGED body near its disc, the leaves further diverge, then body is negatively charged.  However, if leaves collapse, charge G.L.E positively. The first TIME we bring the object close to the GLE, the leaves get charged with the charge of the object, so we are to bring the object closer to the disk the second time to determine the charge of the body, hence;Again bringing charged body near its disc.  If the leaves diverge, then body is positively charged and if the leaves collapse, the body has negative charge.

of Time and Motion Study:Time study is defined as a work measurement technique for recording the TIMES and rates of working for the elements of a specified job carried out under specified conditions and for analysing the data to determine the time necessary for carrying out the job at a defined level of performance.Motion study implies dividing the work into fundamental elements or basic OPERATIONS of a job or a process with the object of eliminating unnecessary or defective elements in a job. After investigating all movements in a job, process or operation it finds out the most scientific and systematic METHOD of PERFORMING the operation or completing the job.

can oscillate in all sorts of ways but a really IMPORTANT form of oscillation is SHM or Simple Harmonic MOTION. An object is undergoing simple harmonic motion (SHM) if; the acceleration of the object is directly proportional to its DISPLACEMENT from its equilibrium POSITION.

nic cleaning uses cavitation bubbles induced by high frequency PRESSURE (sound) waves to AGITATE a LIQUID. The agitation produces high forces on contaminants adhering to substrates like metals, plastics, glass, rubber, and CERAMICS. This action also penetrates BLIND holes, cracks, and recesses.
