An increase in the temperature of a gas that is kept at constant volume is because: B. Energy has been added as heat to the gas.
What is heat?
Heat is also referred to as thermal energy and it can be defined as a form of energy that is transferred from one physical object to another, especially due to a difference in temperature.
Generally, heat is typically transferred between objects with different degrees of temperature and materials that are directly in contact with each other during the process of heat conduction.
For an ideal gas that is kept at constant volume, there is a change in its temperature because energy has been added as heat.
