Question

What is the difference due which thermal energy flows between objects?

Answer 1

Answer:

The Heat Transfer

Explanation:

The transfer or flow due to the difference in temperature between the two objects is called heat. For example, an ice cube has heat energy and so does a glass of lemonade. If you put the ice in the lemonade, the lemonade (which is warmer) will transfer some of its heat energy to the ice.

Heat transfer works by transferring energy from one substance to another via convection, conduction or radiation. Particles in a substance are able to store energy and transfer it to other particles, often in the form of heat.

The three ways that heat can be transferred are conduction, convection and radiation. Conduction is most efficient in solids, convection occurs in liquids and gases and radiation occurs through anything that allows radiation to pass through.

Answer 2

Thermal energy flows between objects due to differences in temperature.

Explanation:

• When there is a difference in temperature between two objects then the heat flows from an object with a higher temperature to the object with lower temperature.
• For example, a cup of warm water has less energy than a tub of warm water.
• Similarly, when a spoon is placed in a hot water cup, the energy will flow from the dip end to the other end due to difference in the temperature.
