Question

The thermal energy in a heat engine is used to move a piston. Which best describes why this is possible?

Answer 1

Answer:

The increase in thermal energy results in an increase in pressure.

Explanation:

From what i remember learning in high school, this is definitely the answer.

Answer 2

Answer:

The increase in thermal energy results in an increase in pressure.

Explanation:

• The increase in entropy is directly related to the increase in temperature. So the thermal energy in heat engine increases the temperature of that surrounding.
• Higher temperature means the kinetic energy of particles is also higher, their vibration is increasing. So it increases the pressure (ideal gas law).
• In this way the increment in the thermal energy in heat engine moves piston by increasing the pressure.
