Calculate the heat required to raise the temperature of 10kg of copper from 20°c to 30°c (specific capacity of copper =400j/kg/k
To calculate the heat required to raise the temperature of a substance, you can use the formula:
Q = m * c * ΔT
Where:
Q = heat (in joules)
m = mass of the substance (in kg)
c = specific heat capacity of the substance (in J/kg/°C)
ΔT = change in temperature (in °C)
Given:
m = 10 kg
c = 400 J/kg/°C
ΔT = 30°C - 20°C = 10°C
Using the formula above:
Q = 10 kg * 400 J/kg/°C * 10°C
Q = 40,000 J/kg/°C * 10 kg * 10°C
Q = 400,000 J
Therefore, the heat required to raise the temperature of 10 kg of copper from 20°C to 30°C is 400,000 joules.
