Step-by-step explanation:

The change in temperature of a subtance can be calculate d using this formula:

Q = m * C * ΔT

ΔT = Q/(m * C)

Where ΔT is the temperature change, Q is the heat absorbed or released, m is the mass of the samle and C is the specifice heat.

We can suppose that we have three samples with the same mass but different substances. We ha.e 1 gram of each substance and their specific heats are:

m = 1 g

C1 = 1 J/(g°C) C2 = 10 J/(g°C) C3 = 100 J/(g°C)

These samples will absorb 1 J of energy and we can calculate the temperature chanee for each substance:

Q = 1 J

Sample 1:

ΔT1 = Q/(m * C1)

ΔT1 = 1 J/(1 g *
