Heat may be defined as the form of energy. The heat can be absorbed during the reaction or heat can be released during the reaction depending upon the time of reaction.
The kilocalorie of heat is used to measure the heating or the metabolization of the food. The kilocalorie of heat means the amount of the heat that are required to raise the 1 gram or kilogram of water by 1 degree celcius. The 1 g of water has been raised by the difference of 1 1 degree celcius in14 °C to 15 °C.
The unit of energy or work is done can be represented in the form of a calorie and since work done result in the increase of temperature therefore calorie can be expressed in terms of heat and temperature.
A calorie in terms of heat can be referred to as the amount of heat required to increase the temperature of 1 g of water upto 1°C that is from 14.5 °C to 15.5 °C.(standard temperature range for calculating calorie).
Similarly, a 1000 cal or 1 kcal can refer to as the amount of heat energy required to increase the temperature of 1 kg of water up to 1°C.
In the given question, since none of the option has provided this, therefore, assuming that cal and kcal are interchangeably used, the Option-A is the correct answer.
