86606 calories of energy was transferred from the 2000gm of food into the water.
Explanation:
1 kilocalorie of energy is required to raise 1 degree of temperature increase. in 1 kg of water.
It is also said that amount of energy or heat released in food combustion is equal to the heat absorbed by water in the combustion chamber.
1 kilocalorie=4.184 kJ
Amount of water =2000g or 2 kg
Temperature change= 44.3-22 degree celsius
= 22.3 degree celsius
2kg*22.3= 44.6 Kilocalorie of energy input.
equation to calculate the energy in calories
q=mc(change in temperature)
specific heat capacity of water is 4.184
= 2*4.184*22.3
q = 186.60 Kj
To convert into gm
186.60*1000
= 186606 calories of energy was transferred from the 2000gm of food into the water.
