How much heat is required to raise the temperature of 100g of copper from 293 kelvin to 373 kelvin(specific heat capacity of copper 400j/kg/k).
heat=mass*specificheat*changeintemp
units: change mass 100g to kg (0.10kg) or change specific heat to j/gK, ie (0.400j/gK )
To calculate the amount of heat required to raise the temperature of a substance, we can use the formula:
Q = m * c * ΔT
Where:
Q is the amount of heat energy (in joules)
m is the mass of the substance (in kilograms)
c is the specific heat capacity of the substance (in joules per kilogram per kelvin)
ΔT is the change in temperature (in kelvin)
Given:
m = 100g = 0.1kg
c = 400 J/kg/K
ΔT = (373K - 293K) = 80K
Now, let's plug these values into the formula:
Q = 0.1kg * 400 J/kg/K * 80K
Q = 3200 J
Therefore, the amount of heat required to raise the temperature of 100g of copper from 293K to 373K is 3200 joules.
