The correct answer is: A. Latent heat.
Latent heat is the heat energy released or absorbed by a substance during a change of state. For example, when water changes from a liquid to a gas (water vapor), it absorbs latent heat. This latent heat is what makes water vapor so important in the Earth’s climate.
Solar energy is the energy that comes from the sun. It is a type of radiant energy that is emitted by the sun and is composed of electromagnetic radiation of different wavelengths. Solar energy can be used to generate electricity, heat water, and power homes and businesses.
Stored heat is the heat energy that is stored in a substance. It is the heat energy that is not used to do work. Stored heat can be released when the substance changes state or when it is heated.
Mechanical energy is the energy of motion. It is the energy that is possessed by an object due to its motion. Mechanical energy can be converted into other forms of energy, such as heat energy or electrical energy.
In conclusion, the correct answer is: A. Latent heat.
