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
