Unit 6.3: Heat Transfer and Thermal Equilibrium
Interpret a particle diagram using arrows to show heat transfer.
-
Draw arrows to show heat flow when a hot metal rod is placed in cooler
water.
-
Explain the direction of heat transfer between two particle systems at
different temperatures.
Justify energy transfer as resulting from collisions between warmer and
cooler particles.
-
Why does heat flow from a hot object to a cold object at the particle
level?
-
Describe how particle collisions increase the energy of cooler
particles.
Assign the direction of heat flow based on temperature data for two
system components.
-
If a 50°C metal is placed in 20°C water, which way does heat flow?
-
Explain how temperature differences determine the direction of energy
transfer.
