Question

Science The specific head of copper is 0.09 callge. How much heat will be required to increase temperature of a piece of copper weighing 70g by 20•c?

​

Answer 1

Answer:

6.3 CAL

Explanation:

The formula for the specific heat (s) is:

s = (q)/(m * ΔT) --- (1)

Where

s = Specific heat = 0.09 cal/g°C

m = mass (make sure it is in GRAMS) = 70g

ΔT = Change in temperature = 21° - 20° = 1°

q = Heat Energy = ?

Plug in the values in the Equation (1):

(1) => q = (70*1*0.09) = 6.3 cal..
