The flow of elements from one area to another
Thermal energy increases as (blank) increases
(a)
Give another name for Thermal energy
(a)
Thermal energy moves from
Cooler to warmer areas
Warmer to cooler areas
Lukewarm to freezing
Thermal energy continues to be transferred from one object to another until
One is hotter
One is colder
Both have the same temperature
They are lukewarm
The amount of thermal energy transferred from one object to another is dependent on
