A 35.0 g piece of copper wire is heated and the temperature of the wire changes from 29.0°C to 76.0°C. the amount heat absorbed is 243 cal. what is the specific heat of copper? you must show all work

0.15cal/g°C

Explanation:

Given parameters:

Mass of copper wire = 35g

T₁  = 29°C

T₂ = 76°C

Amount of heat absorbed  = 243cal

Unknown:

Specific heat of copper = ?

Solution:

The specific heat of a substance is the amount of heat needed to raise the temperature of a unit mass of such substance by 1°C.

We can express this mathematically as;

           C  =  

Where H is the heat supplied

C is the specific heat

m is the mass

T is the temperature(1 is the initial state and 2 is the final state)

     Input the parameters and solve;

         C  =   = 0.15cal/g°C

what is the question?
