Apiece of copper is measured to be at 10°c and 115 grams in mass. if 1300 calories were added to it, what was the final temperature of the copper? 21.3°c 103.5°c 386.8°c 125.6°c 135.6°c

The final temperature of the copper= 39.4°C

Explanation:

mass= 115 g

change in temperature=ΔT=T-10 where T is the final temperature.

specific heat of copper=0.385 J/g °C

Heat energy absorbed= Q=1300 calories

the formula for heat is given by

Q= m C ΔT

1300=(115) (0.385) (T-10)

T-10=29.4

T= 29.4+10

T=39.4°C

Thus the final temperature of the copper= T=39.4°C
