Question

The specific heat capacity of copper is 0.09 cal/g°C. How much energy is needed to flow into a 10-gram sample to change its temperature from 20°C to 21°C? 0.009 cal 0.09 cal 0.9 cal 9 cal

Answer 1

0.9 cal

Step-by-step explanation:

Answer 2

The correct answer is: 0.9 cal

Step-by-step 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) = 10g
ΔT = Change in temperature = 21° - 20° = 1°
q = Heat Energy = ?

Plug in the values in the Equation (1):
(1) => q = (10*1*0.09) = 0.9 cal
