Answer:
Q = 12540 J
Explanation:
It is given that,
Mass of water, m = 50 mL = 50 g
It is heated from 0 degrees Celsius to 60 degrees Celsius.
We need to find the energy required to heat the water. The formula use to find it as follows :
![Q=mc\Delta T](https://tex.z-dn.net/?f=Q%3Dmc%5CDelta%20T)
Where c is the specific heat of water, c = 4.18 J/g°C
Put all the values,
![Q=50\times 4.18\times (60-0)\\Q=12540\ J](https://tex.z-dn.net/?f=Q%3D50%5Ctimes%204.18%5Ctimes%20%2860-0%29%5C%5CQ%3D12540%5C%20J)
So, 12540 J of energy is used to heat the water.

Water expands when it freezes (that's why you should never put closed, fully filled water bottles in the freezer !)
