Answer:
<h3>25.0 grams is the mass of the steel bar.</h3>
Explanation:
Heat gained by steel bar will be equal to heat lost by the water
Mass of steel=
Specific heat capacity of steel =
Initial temperature of the steel =
Final temperature of the steel =
Mass of water=
Specific heat capacity of water=
Initial temperature of the water =
Final temperature of water =
On substituting all values:
<h3>25.0 grams is the mass of the steel bar.</h3>
