Solution

The correct option is B False
According to the kinetic theory of gas when the temperature increases, the vibration of the molecule becomes stronger, thus its amplitude increases due to which expansion in the solid is observed.
Hence, the given statement is false.

Q. The molar heat capacity of oxygen gas at STP is nearly 2.5 R. As the temperature is increased, it gradually increases and approaches 3.5 R. The most appropriate reason for this behaviour is that at high temperatures
(a) oxygen does not behave as an ideal gas
(b) oxygen molecules dissociate in atoms
(c) the molecules collide more frequently
(d) molecular vibrations gradually become effective

Vibrations cause sound. So if there are more vibrations sound will travel faster. In solids molecules are fixed, then how can sound travel faster in solids?

Q. Assertion :Water becomes less dense when the temperature goes from

4^{0} C

0^{0} C

. Reason: The density becomes less and less as it freezes because molecules of water normally form open crystal structures when in solid form.

Q. The molecules in a solid are in a state of continuous vibration. However, these vibrations are not visible to us. This is which type of motion?
