How does an increase in thermal energy affect molecules? They stop moving. They begin to vibrate more. They decrease in temperature. They lose kinetic energy.

In what direction does friction always act?

Heat is added to an open pan of water at 100.0°c, vaporizing the water. the expanding steam that results does 43.0 kj of work, and the internal energy of the system increases by 604 kj. how much energy is transferred to the system as heat?

In an internal combustion engine (either gasoline or diesel), the upstroke of the piston reduces the volume of the cylinder. Using the kinetic theory of matter, what happens to the temperature and pressure of the air/fuel blend in the cylinder? A.
