Question
Air pressure in a car tyre increases during driving. Explain.
✓
Answer
Volume of a car tyre is fixed. During driving, temperature of the gas increases while its volume remains constant. So, according to Charle’s law, at constant volume (V),
Pressure (P) $\propto$ Temperature (T)
Therefore, pressure of gas increases
Pressure (P) $\propto$ Temperature (T)
Therefore, pressure of gas increases
