If 135.7 J of heat are added to 54.0 g of water initially at 25.0 °C . What is the final temperature of the water?

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 :

is final temperature

c is specific heat capacity, for water,

So,

So, the final temperature of the water is 25.6 °C.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
