Asilver block, initially at 58.4∘c, is submerged into 100.0 g of water at 25.0∘c in an insulated container. the final temperature of the mixture upon reaching thermal equilibrium is 26.7∘c. the specific heat capacities for water and silver are cs, water=4.18j/(g⋅∘c) and cs, silver=0.235j/(g⋅∘c).

The mass of the silver block is 95.52 grams.

Explanation:

Heat lost by silver will be equal to heat gained by the water

Mass of silver=

Specific heat capacity of silver =

Initial temperature of the silver =

Final temperature of a silver = =

Mass of water=

Specific heat capacity of water=

Initial temperature of the water =

Final temperature of water =

On substituting all values:

we get,

The mass of the silver block is 95.52 grams.
