1349.13 calories are required in order to raise the temperature of 32g of water from 12°C to 54°C.
what is specific heat capacity?
"The amount of heat required to change the temperature of a unit mass of the substance by one degree" is the definition of specific heat capacity for any substance. This is expressed as: Specific heat capacity is a sort of thermal inertia since it shows how resistant a substance is to changes in temperature.
Water has a specific heat capacity of about 4.2 J/g°C. As a result, to increase 1 gramme of water by 1 degree Celsius, 4.2 joules of energy are required.
By formula,
Q = mcΔT = 32*4.2*42 = 5644.8 J
One calorie= 4.184 joules
thus, Q = 5644.8/4.184 calorie = 1349.13 calories.
Thus 1349.13 calories are required in order to raise the temperature of 32g of water from 12°C to 54°C.
