Naomi is investigating the properties of a solid material. it takes 120 joules to raise the temperature of 10 grams of the material by 5 degrees. what is the specific heat of the material?

When heat energy is supplied to a material it can raise the temperature of mass of the material.
Specific heat is the amount of energy required by 1 g of material to raise the temperature by 1 °C.
equation is 
H = mcΔt
H - heat energy 
m - mass of material 
c - specific heat of the material 
Δt - change in temperature
substituting the values in the equation 
120 J = 10 g x c x 5 °C
c = 2.4 Jg⁻¹°C⁻¹

The answer is letter c
