Q. No.The energy requirement of animals and the energy content of food is expressed in terms of
1. Light energy
2. Heat energy
3. Chemical energy
4. Mechanical energy
1. Light energy
2. Heat energy
3. Chemical energy
4. Mechanical energy
Heat energy is the measure of food content because it is
(1) The ultimate form of all energies
(2) Better to measure
(3) Better to express
(4) The most easy way to write energy calculation

(2) The amount of heat energy required to raise the temperature of 18g of water by 1 degree Celsius
(3) The amount of heat energy required to raise the temperature of 1 mole of water by 0.1degree Celsius
(4) The amount of heat energy required to raise the temperature of 1000g of water by 1 degree Celsius
A bomb calorimeter is
(1) A closed metal chamber filled with carbon dioxide
(2) A open non metal chamber filled with carbon dioxide
(3) A closed metal chamber filled with Oxygen
(4) A closed non metal chamber filled with oxygen
In 1 Kcal, the parameters are
(1) Change in temperature is 1 degree Celsius but water is 100g
(2) Change in temperature is 1000 degree Celsius but water is 1g
(3) Change in temperature is 1degree Celsius but water is 1g
(4) Change in temperature is 1 degree Celsius but water is 1000g
