Answer:
The final temperature of the water is 22.44°C.
Explanation:
Heat lost by tin will be equal to heat gained by the water
Mass of tin =
Specific heat capacity of tin =
Initial temperature of the tin =
Final temperature = =T
Mass of water=
Specific heat capacity of water=
Initial temperature of the water =
Final temperature of water = =T
(Law of Conservation of energy)
On substituting all values:
we get, T = 22.44°C
The final temperature of the water is 22.44°C.
