In This Lesson:
What happens to an object when heat is transferred?
Heat transfers from the hotter object (object with higher temperature) to the cooler object (object with lower temperature) that causes the molecules in object with lower temperature will start to move faster while the molecules of the object with higher temperature will move slower.
Example:
► In the opposite picture:
1. The rock absorbs thermal energy from the Sun rays, so the molecules of the rock move faster.
2. When the lizard stands on the rock, the skin of lizard absorbs thermal energy that is released from the rock.
So, the molecules of the rock will move slower while the molecules in the skin of lizard will move faster.
There are two types of materials according to their ability to transfer thermal energy which are thermal insulators and thermal conductors.
Example:
► Let's see an example that shows the meaning of thermal conductors and thermal insulators.
Properties of heat
