A155 g sample of an unknown substance was heated from 25°c to 40°c. in the process, the substance absorbed 569 calories of energy. what is the specific heat of the substance?

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed= 569 calories

m= mass of substance = 155 g

c = specific heat capacity = ?

Initial temperature = = 25.0°C

Final temperature =  = 40.0°C

Change in temperature ,

Putting in the values, we get:

The specific heat of the substance is
