The amount of heat required to raise the temperature of a substance can be calculated using the formula Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. Here, m = 10 g, c = 0.48 cal/g°C, and ΔT = (-20°C) - (-30°C) = 10°C. Thus, Q = 10 g * 0.48 cal/g°C * 10°C = 48 cal.

The Specific Heat of Ice Is 0
