15. HEAT
•Heat flows according to
temperature differences—
that is, average molecular
kinetic energy differences.

16. HEAT
•The direction of spontaneous energy
transfer is always from a warmer to a
cooler substance.
•The energy that transfers from one
object to another because of a
temperature difference between them
is called heat.

17. CONCEPT CHECK: What
causes heat to flow?

21. THERMAL EQUILIBRIUM
Water seeks a common level with
pressures at equal elevations the
same.The thermometer and its
surroundings reach a common
temperature with the average
kinetic energy per particle the
same.
