Question 7. Asked on :08 October 2020:04:08:20 PM

Why does air pressure in a car tyre increased during driving?

-Added by Shruti Srivastva Physics » Thermodynamics

Answer:

During driving, temperature of air inside increases while its volume remains constant. According to Charle's law, at constant volume V,P∝T. Therefore, pressure of air inside the tyre increases.
