Question

The specific heat of copper is 0.09 cal/ g⁰C. How much heat will be required to increases the temperature of a piece of copper weighing 70 g by 20⁰C​

Answer 1

Answer:

The formula for the specific heat (s) is:

s = (q)/(m* AT) --- (1)

Where

s = Specific heat = 0.09 cal/g °C

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

AT 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
