Answer:
HEAT TRANSFER
Which of the following is true of heat and temperature?
A. When the temperature of an object is high the molecules of an object are moving.
B. The kinetic energy of a hot object is higher compared to a cold object.
C. Ice cubes melt when placed in a glass of water because the heat from the ice cubes transfer to the water.
D. A cup of boiling water and a bucket of boiling water has the same amount of heat.
Definition :
- Heat is transfer energy to another physical system and heat is a form of energy that can be transferred.
Why :
- When the heat is the flow of energy from a higher temperature object to a lower temperature object.
- When the heat transfer continues until the two objects have reached thermal equilibrium and are at the same temperature.
- When the heat can move from one point to another.
Three Ways to Transfer a Heat :
- Conduction
- Radiation
- Convection
