Question

Thermal energy moving from a warmer object to a cooler object is called

• A. heat Transfer
• B. specific heat
• C. temperature
• D. thermal expansion.

Answer 1

The correct option is A

heat Transfer

Explanation for correct answer: Option(A)

Heat:

1. Heat is a form of energy, which cannot be seen but can be sensed.
2. Heat transfer, it is the process of transfer of heat from the high-temperature body to a low temperature one.

Hence, Thermal energy moving from a warmer object to a cooler object is called heat Transfer.

Explanation for Incorrect answer:

1. Option(B): specific heat: It is amount of heat required to increase the temperature of a body by $1^{o}C$
2. Option(C): temperature: The quantity used to compare the hotness or coldness of bodies is known as temperature.
3. Option(D): thermal expansion: The most common change caused by heat is expansion, called then expansion. Matter increases in volume when there is an increase in temperature.
