What is the calorific value of water?a)10 joules/calorieb)0 joules/cal...
Calorific value is the amount of heat energy released when a substance is burned completely. It is measured in units of energy per unit of mass, such as joules per gram or calories per gram. The calorific value of water refers to the amount of heat energy released when water is burned.
Explanation:
- The calorific value of water is zero joules/calorie.
- Water is a stable compound that cannot be burned or oxidized in the same way as other substances, such as fuels or food.
- When water is heated, it undergoes a phase change from a liquid to a gas, but this process does not involve combustion or the release of heat energy.
- Water can be used to absorb heat energy or release heat energy through processes such as evaporation or condensation, but these processes do not involve the burning of water.
- The calorific value is used to measure the energy content of substances that can be burned or oxidized, such as fuels or food, but it is not applicable to water.
In summary, the calorific value of water is zero joules/calorie because water cannot be burned or oxidized to release heat energy.
