The specific heat of copper is 0.385 J/g·°C. What equation would you use to calculate the amount of heat needed to raise the temperature of 0.90 g of copper from 9°C to 26°C?

Answer: Q = m c ΔT

Explanation:

Amount of heat required to raise the temperature of an object is give by the equation:

Q = m c ΔT

Where, m is the mass of the object, c is the specific heat and ΔT is the rise in temperature.

It is given that the specific heat of copper is c =.385 J/g°C

Mass of copper, m = 0.90 g

Change in temperature, ΔT = 26°C - 9°C = 17°C

Then amount of heat required to raise the temperature of given amount of copper is:

Q = m c ΔT ⇒ Q = 0.90 g *.385 J/g°C * 17°C = 5.89 J

Thus, 5.89 J is needed to raise the temperature of 0.90 g of copper from 9°C to 26°C.
