Either the temperature will increase, or it will remain the same. In the latter case, there is a phase change, as when ice melts.
If the energy is heat, the water will warm up. If it is kinetic, like throwing it against the wall, the glass will absorb the energy and probably smash into bits.
When you hold a snowball in your hands, the heat energy produced by your hands is transferred into the fusion of ice to water. Fusion is an endothermic reaction.
That is possible when there is a change of state. For example, if you have ice at its melting point, or a mixture of ice and water at its melting point, if you add heat, the energy will be used to melt the ice, not to increase the temperature.
Heat energy transfers from your hand to the ice. This is because heat always passes from the cooler object to the hotter object. The ice gains heat energy, so it heats up.

If a sufficient amount of energy is added to a glass of ice water, the ice will melt, and if a sufficient amount of energy is removed, the water will freeze solid.
it melts
The addition of thermal energy, or heat, if you prefer, will turn solid water (ice) into a liquid by melting it.
its gets cold Actually the ice gets warmer. Its the water that gets cold.
Then it will either get hotter, or its phase will change (as when ice melts).
As water and ice have different temperatures, if we add them together then there will be an exchange of heat, due to which ice starts melting and water becomes cold. The heat required to melt the molecules of ice is provided by the molecules of water and this heat is the latent heat of fusion.
Heat because Ice and water would thaw out and begin to heat up
Heat is added to ice to make it melt.
The energy is used to break down hydrogen bonds between the water molecules making up the ice, during which there is no temperature change. Then the energy is used to change the ice into the liquid phase. Once the phase change is complete, the temperature will increase.
Heat energy would flow from the hand to the ice, unless the hand is colder than the ice, in which case the heat energy would flow from the ice to the hand.
