You are given a sample of metal and asked to determine its specific heat. you weigh the sample and find that its weight is 27.2 n . you carefully add 1.45×104 j of heat energy to the sample and find that its temperature rises 16.0 ∘c

c=326.5177 J/kg.K

Specific heat is c=326.5177 J/kg.K

Explanation:

In order ti find the specific heat, we will proceed as follow:

Formula we are going to use is:

Where:

Q is the heat energy added

m is the mass of sample

c is the specific heat

is the temperature Rise.

First we will find the mass:

Weight=m*g  (g is gravitational acceleration=9.8 m/s^2)

Rearranging above formula:

c=326.5177 J/kg.K

Specific heat is c=326.5177 J/kg.K
