A food provides enough energy to raise the temperature of 2000 grams of water by 10°c. how many kilocalories does it contain?
Musya8 [376]

A food provides enough energy to raise the temperature of 2000 grams of water by 10°c contains 20 KCa.

1 Calorie is the amount of heat needed to elevate one gram of water to one degree Celsius temperature at one atmosphere of pressure.

The term "kilocalorie" is used to describe the amount of energy needed to increase 1 L of water's temperature by one degree Celsius at sea level.

Given

Mass of water (m) = 2000 g
Temp raise (ΔT) = 10°C

Heat capacity of water (C) =  1 calorie/g-C

Formula used

Heat (ΔH) = m × C × ΔT

                = 2000 × 10 = 20000 C

In Kilo calories

20000 C = 20000/1000 = 20 KCa

Hence, a food provides enough energy to raise the temperature of 2000 grams of water by 10°c contains 20 KCa.
