3000 Joules of energy in the form of heat are added to a copper block with a mass of 1 kg. What is the blocks temperature change?
To find the temperature change of the copper block, we need to use the equation:
Q = m * c * ΔT
Where:
Q = Heat energy (in Joules)
m = Mass of the copper block (in kg)
c = Specific heat capacity of copper (in J/kg·°C)
ΔT = Change in temperature (in °C)
In this case, we know that Q = 3000 Joules, m = 1 kg, and the specific heat capacity of copper is approximately 387 J/kg·°C.
Plugging the given values into the equation:
3000 = 1 * 387 * ΔT
Dividing both sides by 387:
ΔT = 3000 / 387
Evaluating this expression, we get:
ΔT ≈ 7.75 °C
Therefore, the temperature change of the copper block is approximately 7.75 °C.
