How much energy is required to raise the temperature of a 2.0kg object with a specific heat capacity of 4200J/(kg ∘ C) by 10 ∘ C?
Question
How much energy is required to raise the temperature of a 2.0kg object with a specific heat capacity of 4200J/(kg ∘ C) by 10 ∘ C?
Solution
The energy required to change the temperature of an object can be calculated using the formula:
Q = mcΔT
where: Q = heat energy (Joules, J) m = mass (kilograms, kg) c = specific heat capacity (Joules per kilogram per degree Celsius, J/kg°C) ΔT = change in temperature (degrees Celsius, °C)
Given: m = 2.0 kg c = 4200 J/kg°C ΔT = 10°C
Substitute the given values into the formula:
Q = (2.0 kg) * (4200 J/kg°C) * (10°C)
Q = 84000 J
Therefore, 84000 Joules of energy is required to raise the temperature of a 2.0 kg object with a specific heat capacity of 4200 J/kg°C by 10°C.
