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.
