Question

Assertion (A): Temperature of a body can be increased by passing sound waves through it. Reason (R): Heat and sound are different forms of energy
(a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true, but R is not the correct explanation of A
(c) A is true but R is false.
(d) Both A and R are false.​

Answer 1

Answer:

c) A is true but R is false

Answer 2

Answer:

(A): Note that the air molecules already have a motion that is somewhat disordered. In other words, air through which sound is traveling already contains some amount of heat. When some of the sound wave is converted to heat, the motion of the air molecules becomes more disordered and the amount of heat increases.

(R):Thermal energy is created from the vibration of atoms and molecules within substances. The faster they move, the more energy they possess and the hotter they become. Thermal energy is also called heat energy.

A is true R is false I think I don't know,I have have u r answer.
