How much heat is needed to raise the temperature of 75 grams of copper from 35„aC to 57„aC? The specific heat of copper is 0.385 J/g „aC.
To find out how much heat is needed to raise the temperature of a substance, you can use the formula:
Q = m * c * ΔT
Where:
Q = Heat transferred (in joules)
m = Mass of the substance (in grams)
c = Specific heat capacity of the substance (in J/g°C)
ΔT = Change in temperature (in °C)
Given:
Mass of copper (m) = 75 grams
Specific heat of copper (c) = 0.385 J/g°C
Change in temperature (ΔT) = 57°C - 35°C = 22°C
Now substitute these values into the formula:
Q = 75 g * 0.385 J/g°C * 22°C
Calculating this:
Q = 595.5 J
Therefore, it takes 595.5 joules of heat to raise the temperature of 75 grams of copper from 35°C to 57°C.
