Calculate the specific heat capacity of a new alloy if a 15.4 g sample absorbs 297 Joules when it is heated from 5.0 °C to 20.7 °C. The key assumes you are giving your answer in Joules/g°C and rounding to 2 or 3 sig figs

The specific heat of alloy is

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 = 297 J

m= mass of substance = 15.4 g

c = specific heat capacity = ?

Initial temperature = = 5.0°C

Final temperature =  =20.7°C

Change in temperature ,

Putting in the values, we get:

The specific heat of alloy is
