Vedclass · Answer

(B) During driving,the friction between the tyre and the road,along with the continuous compression and expansion of the tyre,generates heat. This increases the temperature of the air trapped inside the tyre. According to Gay-Lussac's Law,for a fixed mass of gas at constant volume,the pressure $P$ is directly proportional to its absolute temperature $T$ $(P \propto T)$. Therefore,as the temperature increases,the air pressure inside the tyre increases. This confirms the Assertion is correct. Regarding the Reason,absolute zero temperature $(0 \ K)$ is defined as the temperature at which the classical kinetic energy of gas molecules becomes zero. However,in quantum mechanics,the zero-point energy exists even at absolute zero. Thus,the statement that 'Absolute zero temperature is not zero energy temperature' is scientifically correct. However,the Reason does not explain why the pressure increases in a car tyre; the pressure increase is due to the temperature rise caused by friction,not the nature of absolute zero energy. Therefore,both are correct,but the Reason is not the correct explanation of the Assertion.

$Assertion :$ Air pressure in a car tyre increases during driving.
$Reason :$ Absolute zero temperature is not zero energy temperature.
