A kilocalorie of heat is required to raise the temperature of A) 1 g of water from 14 °C to 15 °C. B) 1 g of water by 10 °C. C) 10 g of water by 10 °C. D) 100 g of water by 10 °C. E) 100 g of water by 100 °C.

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.

Thus, the correct answer is option (A).

A kilocalorie of heat is required to raise the temperature of - D) 100 g of water by 10 °C

The measurement of heat is called calorimetry. The calorie, or gram calorie, is the quantity of heat required to raise the temperature of 1 gram of pure water

The kilocalorie, or kilogram calorie, is the quantity of heat required to raise the temperature of 1 kg of pure water 1°C.

1 kilogram is equal to 1000 grams

1 kilocalorie raises 1000 grams to = 1 degree

then, it will raise 100 grams to= 10 degrees

Thus, a kilocalorie of heat is required to raise the temperature of - D) 100 g of water by 10 °C
