tion:Chromium is coated in kitchen GAS BURNERS because it prevents corrosion. The HARDNESS of the gas burners is also increased by giving a coat of chromium or hard chrome PLATING them. ... But the primary purpose is to prevent corrosion due to high heat.

Perturbed gas excitation A COLLECTION of MOLECULES forming a gas can be considered in an excited state if ONE or more molecules are elevated to kinetic energy LEVELS such that the resulting velocity distribution departs from the equilibrium Boltzmann distribution

What have to FIND in this

here is ur answer!!!Explanation:PLZ LOOK at above PIC. hope this will HELPS U...be happy....

Relative DENSITY is the RATIO of the density of the substance to the density of water.We know that, density of water is 1gm/cm3=103kg/m3So, relative density of ALCOHOL = 1000800 = 0.8

A mole corresponds to the MASS of a substance that CONTAINS 6.023 x 1023 particles of the substance. The mole is the SI unit for the amount of a substance. Its symbol is MOL. By definition: 1 mol of carbon-12 has a mass of 12 grams and contains 6.022140857 x 1023 of carbon atoms (to 10 significant figures).

Please answer this quickly, it's urgent*If the vibration frequency of the star is GIVEN by the equation f = KR^a RHO^b G^c, where f is frequency, R is radius of star, rho is DENSITY of star, G is universalgravitational constant and K is dimensionless constant, then correct statement is1. a=1, a+b+c=22. b=c=1/2, b+c=13. b=1/2, c=1/2, a+b+c=04. c=b=1/2, a=1

g Newton’s Second Law of MotionNewton’s second law states that the acceleration of an object depends upon two VARIABLES – the net force acting on the object and the mass of the object. The acceleration of the body is directly proportional to the net force acting on the body and inversely proportional to the mass of the body. This means that as the force acting upon an object is increased, the acceleration of the object is increased. LIKEWISE, as the mass of an object is increased, the acceleration of the object is decreased.Newton’s second law can be formally STATED as,The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.This statement is expressed in equation FORM as,The above equation can be REARRANGED to a familiar form asSince force is a vector, Newton’s second law can be written asThe equation shows that the direction of the total acceleration vector points in the same direction as the net force vector.

ans 1 Newton's law of universal GRAVITATION is usually stated as that every particle attracts every other particle in the universe with a force that is DIRECTLY proportional to the product of their masses and INVERSELY proportional to the square of the distance between their centers. EXPLANATION: ans 2The Universal Law of Gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

Water is the only substance where all three states can be readily OBSERVED in everyday life: solid water as ice, liquid water in a water fountain, and GASEOUS water as STEAM. CARBON dioxide is a GOOD example of a substance which can be a liquid, but only when it is under pressure.

ion of Sound    Sound bounces off a solid or a liquid like a rubber ball bounces off a wall. Like light, sound gets reflected at the surface of a solid or liquid and follows the same laws of reflection as you have studied in earlier classes. The directions in which the sound is incident and is reflected make equal angles with the normal to the reflecting surface at the POINT of incidence, and the three are in the same plane. An obstacle of large size which may be polished or rough is needed for the reflection of sound waves.    Activity  • Take two identical pipes, . You can make the pipes using chart paper. The length of the pipes should be sufficiently long as shown.• Arrange them on a table NEAR a wall.• Keep a clock near the open end of one of the pipes and try to hear the sound of the clock through the other pipe.• Adjust the position of the pipes so that you can best hear the sound of the clock.• Now, measure the angles of incidence and reflection and see the relationship between the angles.• Lift the pipe on the right vertically to a small height and observe what happens.      Echo  If we shout or clap near a suitable reflecting object such as a tall building or a mountain, we will hear the same sound again a little later. This sound which we hear is called an echo. The sensation of sound persists in our brain for about 0.1 s. To hear a distinct echo the time interval between the original sound and the reflected one must be at least 0.1s. If we take the speed of sound to be 344 m/s at a given temperature, SAY at 22 ºC in air, the sound must go to the obstacle and reach back the ear of the listener on reflection after 0.1s. Hence, the total DISTANCE covered by the sound from the point of generation to the reflecting surface and back should be at least (344 m/s) × 0.1 s = 34.4 m. Thus, for hearing distinct echoes, the minimum distance of the obstacle from the source of sound must be half of this distance, that is, 17.2 m. This distance will change with the temperature of air. Echoes may be heard more than once due to successive or multiple REFLECTIONS. The rolling of thunder is due to the successive reflections of the sound from a number of reflecting surfaces, such as the clouds and the land.          TRY IT OUT!!!MARK AS" BRILLIANT"!

Potential ENERGY is the stored energy in an object or system because of its position or configuration. KINETIC energy of an object is RELATIVE to other MOVING and stationary OBJECTS in its immediate environment. Potential energy is not relative to the environment of an object.Hope it helps you......Explanation:
