how much heat is required to heat 500 g of copper from 20 degree celsius to 80 degree celsius? specific heat of copper is 0.093 cal/g- degree celsius
To calculate the amount of heat required to heat a substance, we use the formula:
Q = m × c × ΔT
Where:
Q is the amount of heat (in calories)
m is the mass of the substance (in grams)
c is the specific heat capacity of the substance (in cal/g-°C)
ΔT is the change in temperature (in °C)
In this case, we want to find the amount of heat required to heat 500 grams of copper from 20°C to 80°C.
First, let's calculate the change in temperature:
ΔT = Final temperature - Initial temperature
ΔT = 80°C - 20°C
ΔT = 60°C
Now, we can calculate the amount of heat using the formula:
Q = m × c × ΔT
Q = 500 g × 0.093 cal/g-°C × 60°C
Let's perform the calculation:
Q = 500 g × 0.093 cal/g-°C × 60°C
Q = 2790 cal
Therefore, it requires 2790 calories of heat to heat 500 grams of copper from 20°C to 80°C.
