Answer:
The final temperature of the water is 25.6 °C.
Explanation:
We have,
Heat added to water is 135.7 J
Mass, m = 54 g
Initial temperature was 25 °C
It is required to find the final temperature of the water. The heat added when temperature is increased is given in terms of specific heat capacity as :
[tex]Q=mc(T_f-T_i)[/tex]
[tex]T_f[/tex] is final temperature
c is specific heat capacity, for water, [tex]c=4.184\ J/g^{\circ} C[/tex]
So,
[tex]T_f=\dfrac{Q}{mc}+T_i\\\\T_f=\dfrac{135.7}{54\times 4.184}+25\\\\T_f=25.6^{\circ} C[/tex]
So, the final temperature of the water is 25.6 °C.
