Thermal Energy Transfer Scenarios

When you touch a hot stove, heat is transferred from the stove to your hand. This transfer of heat occurs through direct contact between the hot stove and your skin.

If you touch a cold window during winter, heat from your hand is conducted through

the glass to the colder air outside, resulting in the sensation of coldness.

If you place a cold metal spoon in a cup of hot soup, the spoon gradually becomes warmer as heat is transferred from the hot soup to the spoon.

When you use a metal pan to cook food on a stove, the heat from the stove goes through the pan and transferred to the food, causing it to cook.

Holding somebody else’s hand will often transfer body heat from their hand to yours or vice versa - it depends on whose hand is feeling warmer or colder at that moment.

When you boil water in a pot on a stove, the heat from the burner causes the water at the bottom of the pot to become hotter and less dense. The hotter water rises to the top, while the cooler and denser water near the surface sinks, creating a circulating flow of water that transfers heat throughout the pot.

On a hot summer day, warm air near the ground rises and is replaced by cooler air from above. This natural movement of air, known as air currents, facilitates the transfer of heat from the ground to the atmosphere.
