A 28.2 g sample of nickel is heated to 99.8 ºC and placed in a coffee cup calorimeter containing 150.0 g of water at a temperature of 23.5 ºC. After the metal cools, the final temperature of the metal and water is 25.0 ºC.

Calculate the heat capacity of nickel, assuming that no heat escapes to the surroundings or is transferred to the calorimeter.

Answer :

The specific heat capacity of the nickel metal is 0.45.

What is the number of heat capacity of the nickel?

Let us recall that the specific heat capacity is used to describe the amount of the quantity of heat that is able to cause the temperature of a unit mass of a substance to increase by 1 kelvin.

Now we know that the heat that is lost by the metal is equal to the heat that is gained by the water as such we have;

mcwdT = -mcmdT

cm = mcwdT/mdT

cm = Heat capacity of the metal

cw = Heat capacity of the water

m = mass of the metal and the water

dT = temperature change

To obtain the heat capacity;

cm = 150 * 4.2 * (25 - 23.5)/-28.2 * (25.0 - 99.8)

cm = 945/2109.4

cm = 0.45
