How much energy is required to raise the temperature of 11.3 grams of solid magnesium from 22.5 C to 35.1 C?

Answer 1

Look up the specific heat (c) of solid magnesium in units of J/(kg°C). Then

Q = mcΔT

Q = required energy in joules

m = mass of magnesium = 0.0113 kg

c = ? J/(kg°C) (look it up)

ΔT = 35.1°C - 22.5°C

Plug in all the numbers and get Q in joules.
