What is the energy change when the temperature of 10.0 grams of solid graphite is decreased from 39.0 °C to 23.8 °C?

Question

specific heat to energy or temperature.

Answer 1

The formula we would want to use is q = mC∆T

q = heat = ?

m = mass = 10.0 g

C = specific heat of graphite (you need to look it up, or it should be provided)

∆T = change in temperature =23.8 - 39.0 = -15.2º

Plug in the values and solve for q. It will have a negative value since the temperature is decreasing meaning heat is being given off to the surroundings (∆H)
