LAw of conservation of Energy is an important concept to solve this problem. The energy released is equal to the energy absorbed. 
Ice undergoes latent heat. MEaning there is a change in phase but not temperature and the energy is solved by (enthalpy of fusion)(mass) = 333.5J/g)(8.5g). =2834.75J. 
This is equal to the energy released by the water. The energy is computed by (mass)(specific heat of water)(temperature change) = (255g)(4.16J/gK)(T)

Final equation is: 
2834.75 = 255(4.16)(T) 
T = 2.67K

<h3>The last equation is: </h3>

2834.75 = 255 (4.16) (T)

T = 2.67K

<h2>Further Explanation </h2>

The law of conservation of energy is an important concept for solving this problem. The energy released is enough for the energy absorbed.

Ice undergoes a heat of transformation. This means there is a phase change but not temperature and therefore energy is resolved by (fusion enthalpy) (mass) = 333.5J / g) (8.5g). = 2834.75J.

This is enough for the energy released by water. Energy calculated by (mass) (specific water heat) (temperature change) = (255g) (4.16J / gK) (T)

In physics, the law of conservation of energy states that the amount of energy from a closed system does not change - it will remain the same. That energy cannot be created or destroyed by humans, but it can change from one form of energy to another. For example, chemical energy can be converted into kinetic energy in dynamite explosions.

The most common definition of energy is a work that can be carried out by certain forces (gravity, electromagnetic, etc.).

Energy is a conserved quantity. Because of various forces, such as gravity, electricity, heat and so on, energy has various forms.

<h3>Energy can be grouped into two main categories, namely: </h3>
  • Kinetic energy
  • Potential energy
