Engines: Motive Power Types: Motive power fundamental principles

Pressure & temperature	The pressure and temperature of a gas are linked. As pressure goes up and down, so does temperature.
Pressure & volume	Pressure and volume are in inverse relation. As one rises, the other falls.
Temperature & energy	The temperature of a gas is a measure of how much energy it has.
Understanding power and torque	When an piston is forced down the cylinder during the power stroke it applies the force to the connecting rod. The connecting rod then causes the crankshaft to turn. The rotational force applied to the crankshaft is called torque.
