Answer:
temperature of water is 24 degree
temperature of copper is 26.89 degree
Explanation:
given data
copper mass = 100 gram
temperature = 200 degree
water mass = 400 gram
temperature = 20 degree
specific heat of copper = 387 J/kg = 0.387 J/g
to find out
temperature of copper and water
solution
we know in equilibrium condition heat is loss by copper is equal to heat is gain by water and we consider here x is temperature so equation is
mcΔt for copper = mcΔt for water ..................1
100 (0.387) (200-x) = 400 (4.187) ( x-20) ..........2
solve it and we get x
x = 24.06
so here temperature of water is 24 degree
and put this value in equation 2 for water we get temperature of copper
100 (0.387) (200-x) = 400 (4.187) ( x-20)
100 (0.387) (200-x) = 400 (4.187) ( 24-20)
solve it and we get
x = 26.89 degree
so temperature of copper is 26.89 degree
