How many Btu of heat must be added to 1200 lb of copper to raise its temperature from 100°F to 450°F
-specific heat for copper is 0.092-
To find out how many BTU of heat must be added to the copper, you can use the formula:
Q = m * c * ΔT
Where:
Q is the heat energy (in BTU),
m is the mass of the copper (in pounds),
c is the specific heat capacity of copper (in BTU/lb°F), and
ΔT is the change in temperature (in °F).
Given values:
m = 1200 lb
c = 0.092 BTU/lb°F
ΔT = 450°F - 100°F = 350°F
Substituting the values into the formula, we have:
Q = 1200 lb * 0.092 BTU/lb°F * 350°F
Now, we can calculate:
Q = 1200 * 0.092 * 350
Q = 38,640 BTU
Therefore, you would need to add 38,640 BTU of heat to the 1200 lb of copper to raise its temperature from 100°F to 450°F.
