How much energy is transferred when 30.0
g of water is cooled from 25.0 °C to 12.7 °C.

Heat transferred, Q = 1542.42 J

Explanation:

Given that,

Mass of water, m = 30 grams

Initial temperature,

Final temperature,

We need to find the energy transferred. The energy transferred is given by :

c is specific heat of water, c = 4.18 J/g °C

So,

So, 1542.42 J of energy is transferred.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
