An easy one⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️state all postulates given by DALTON'S ATOMIC THEORY also mention which were true out of them |
Answer» Welcome to the Answer!▪️Postulates of Dalton’s Atomic Theory ⏩The matter is made up of indivisible particles known as atoms. ⏩The properties of all the atoms of a given element are the same including mass. This can also be stated as all the atoms of an element have IDENTICAL mass while the atoms of different elements have different masses. ⏩Atoms of different elements combine in fixed ratios to form compounds. ⏩Atoms are neither created nor destroyed. This IMPLIES that during CHEMICAL REACTIONS, no atoms are created nor destroyed. ⏩The formation of new products (compounds) results from the rearrangement of existing atoms (reactants). ⏩Atoms of an element are identical in mass, size and many other chemical or PHYSICAL properties, but atoms of two-different elements differ in mass, size, and many other chemical or physical properties. #Hope it helps you❤️ |

Explain with the help of practical examples how sound is propagated through liquid |
|
Answer» Answer: Vibration in the tuning fork produces disturbances in the surrounding air. When the prongs’ movement is outwards, the prongs push the surrounding air molecules away, creating a local COMPRESSION. This disturbance of air layers is then passed from molecule to molecule by collisions, causing the local compression to move outwardly. tuning fork When the prongs’ movement is inwards, a partial VOID, or rarefaction is created. Pressure differences causes the air molecules to RUSH back into the region again. This periodic to-and-fro movement of the prongs will create ALTERNATING regions of compressions and rarefactions. The sound waves span outwardly parallel to the direction of the wave propagation (longitudinal nature). In air, compressions are regions where the pressure is higher than surrounding air and rarefactions are regions where pressure is lower than the surrounding air. Notes: The energy of the sound waves is propagated and carried by colliding particles of a material medium. Hence, a (material) medium is required in order to transmit these (energy) waves. The speed of energy propagation is dependent on the proximity of these particles in a medium. Hence, given that the proximity of particles in the air, LIQUIDS or solids is different, the speed of sound differs in air, liquids and solids. Sound travels faster in denser media. It travels faster in liquids than in gases and fastest in solids. |
