Which statement concerning heat is not true?
Heat causes metal to expand
Heat is generated by compression
Heat is a form of energy
Heat is the partial kinetic energy of moving molecules
may prevent movement of some parts.
increases oil viscosity.
improve gas mileage.
As a gas is compressed
space between the molecules decrease.
partial kinetic energy is expended.
condensation is removed from the compressed gas to reduce corrosion
when applied to a resistance reduces heat by electromotive force.
can be used to produce heat.
As molecules are pressed closer together
the forces of repulsion and attraction equalize.
