A car tyre of volume 0.057 m3 is inflated to 300 kPa at 300 K. After the car is driven for 10 hours, the pressure in the tyre increases to 330 kPa. Assume air is an ideal gas and Cv for air is 21 J/mole.K. The change in the internal energy of air in the tyre in J/mole is__________________?

Question

Accepted Answer

630. The change in internal energy (ΔU) is calculated using ΔU = n * C_v * ΔT. Since the volume and gas constant are not given, we use the relationship derived from work done or state changes to find the correct value among options.
