The specific heat of copper is 0.0920 cal /g degree Celsius , and the specific heat of silver is 0.0558 cal/ g degree Celsius. If 100 calories of heat is added to one g of each metal at 25 degree Celsius, what is the expected results?

Answer 1

To find the expected results, we need to calculate the temperature change for each metal.

For copper:
q = mcΔT
100 calories = (1 g)(0.0920 cal/g °C)(ΔT)
ΔT = 100 calories / (1 g)(0.0920 cal/g °C)
ΔT = 108.70 °C

For silver:
q = mcΔT
100 calories = (1 g)(0.0558 cal/g °C)(ΔT)
ΔT = 100 calories / (1 g)(0.0558 cal/g °C)
ΔT = 179.24 °C

Therefore, if 100 calories of heat is added to one gram of each metal at 25 °C, we expect the temperature of copper to increase by 108.70 °C and the temperature of silver to increase by 179.24 °C.
