Answer:
Final temperature of water = 31.2° C
Explanation:
Let the final temperature of water be T degrees
Concept: By energy conservation law
Heat lost by the silver = heat gained by water
Heat lost be silver Q1 = m1c1ΔT1
Q1 = 45.2/1000Kg×2.36J/KgK×(101-T)
Heat gained by water Q2 = m2c2ΔT2
Q2 = 300/1000Kg×4.186J/KgK(T-30.6)
Since, Q1=Q2
⇒ 45.2/1000Kg×2.36J/KgK×(101-T) = 300/1000Kg×4.186J/KgK(T-30.6)
Solving we get T = 31.2° C
Therefore, final temperature of water = 31.2° C
