Answer 2

Answer:

Heat energy is transferred from one body to another body. Naturally, the heat energy is transferred from hotter body to the colder body. For example, heat will be transferred from a body of 30 degree Celsius to 20 degree Celsius. This makes a body cold or warm.

Explanation:

• Temperature is defined as the hotness or coldness of body. It can be measured using thermometer or some other equipment.
• The rise of temperature can be done by providing more heat energy to a body, and if you want to make a body colder we have to extract heat from it.
• If a hot body is kept in an environment or at room temperature it continuously transfer heat from itself to the surrounding. The change in room temperature can be of negligible amount this is because a body is much smaller as compared to room.
