To calculate the heat lost by water, we can use the formula:
where:-
is the heat lost or gained,-
is the mass of the substance,-
is the specific heat capacity of the substance,-
is the change in temperature.Given:- Mass of water (
) = 149 g- Specific heat capacity of water (
) = 4.18 J/g°C- Initial temperature of water (
) = 50°C- Final temperature of the mixture (
) = 26°CThe change in temperature for water (
) is:
Now, we can calculate the heat lost by water:
Therefore, the heat lost by water is
.The correct answer is:a.
