Answer:
Q = 114895 J
Explanation:
To find the thermal energy gained by the ice you use the following formula:

m: mass of the ice = 0.250kg
T2: final temperature = 22°C
T1: initial temperature = -8.0°C
Hf: heat of fusion of water = 3.34*10^5 J/kg
c: specific heat of water = 4186 J/kg
By replacing the values of the parameters you have:

where you have considered that ice melts completely
Explanation:
Below is an attachment containing the solution.
Use the equation potential energy =m*g*h
m-mass,
g-gravitational acceleration,
h-height
Potential energy = 2*10*10
=200

This is the unit of the energy
