The amount of thermal energy required to change the temperature of a substance is proportional to its mass and its specific heat capacity. The specific heat capacity of copper is 0.385 J/g°C.
To find the change in temperature, we can use the following formula:
ΔT = Q / (m * c)
where ΔT is the change in temperature, Q is the amount of thermal energy removed, m is the mass of the copper block, and c is the specific heat capacity of copper.
Substituting the given values, we get:
ΔT = 24,600 J / (0.94 kg * 0.385 J/g°C)
ΔT = 65.42°C
Therefore, the temperature of the copper block would decrease by approximately 65.42°C when 24,600 J of thermal energy is removed from it.
