Conduction - requires direct contact or particle to particle transfer of energy; usually occurs in solids 2. Convection - heat moves in currents; hot air rises and cold air falls; only occurs in fluids 3. Radiation - heat waves travel through empty space, no matter needed; sun Thermal ...

What is cold? -Heat is the movement, or transfer of thermal energy. -Cold is the lack of thermal energy. The direction of thermal energy flow is always from warmer to colder. Ex. Hand touches a hot stove – hand gets burned Ex. Hand touches ice – ice starts to melt. ...
The warmer object will cool down and the cooler object will warm up until they are the same temperature. When Equilibrium, or a balance in temperature, is achieved heat transfer will stop. Adding thermal energy or “Heating” particles increases their motion, resulting in an increase of temperat...
