When a car is parked in hot sunlight, the temperature of the car’s seats increases and the thermal energy of the seats increases.

Explanation:

The radiation of the Sun heats the air trapped inside the car which eventually heats everything inside the car including the seats of the car. The temperature of the seat rises.

The thermal energy is related to the kinetic energy of the constituent particles of a body. When a body is heated up, its temperature increases which in turn increases the kinetic energy of the particles thereby increasing the thermal energy of the body.

Here, rise in temperature of the seats increases the thermal energy of the seats.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

im sorry i dont know
