Answer:

Q = -5913.6 J

Explanation:

Given that,

Mass of the sample, m = 44 g = 0.044 kg

Initial temperature = 18°C

Final temperature = -14°C

We need to find the energy involved in this change. The energy involved in this process is given by :

[tex]Q=mc\Delta T[/tex]

c is specific heat of water

[tex]Q=0.044\times 4200\times (-14-18)\\\\Q=-5913.6\ J[/tex]

So, 5913.6 J of energy is involved in this change.
