Question
50 g of copper is heated to increase its temperature by 10∘C. If the same quantity of heat is given to 10 g of water, the rise in its temperature is:
Specific heat of copper is 420 J kg−1 ∘C.
Specific heat of copper is 420 J kg−1 ∘C.
Answer: Option A
:
A
Same amount of heat is supplied to copper and water.
mcccΔTc=mwcwΔTw
ΔTw=mcccΔTcmwcw
ΔTw=50×10−3×420×1010×10−3×4200
ΔTw=5∘C
