explain why the temperature stays constant when ice is chenging into water?

Answer 1

When the ice is melting, the energy that would normally go into raising the temperature is being used to break the bonds that keep it solid. When the bonds are broken, the temperature of the resulting water starts to rise again.

Answer 2

When ice reaches 0 c , it absorbs energy . This energy absorbed in the form of heat is required by the ice to change its state. It is known as latent heat of fusion (for the reverse process)
During this process ice at 0 c changes to water at 0 c. Thus the temperature remains constant.

Answer 3

When the phase "changes" (yes, of course it does change) from ice to water, it takes a certain anount of heat, called the latent heat.

The heat energy is being absorbed by the ice/water, but instead of manifesting itself as a rise in temperature, it goes into the energy required to change the phase. Once that energy requirement is satisfied, then the temperature of the liquid begins to rise.

Answer 4

Ice does not "change" into water. Ice is water in a different form. I would suppose the temperature does not change as it is melting because the temperature is constant. However, as the temperature around the water changes it will affect the temperature of the water in its liquid form.

Answer 5

Because it takes about 79 cal / g to convert water into ice. This is called the latent heat of fusion. There is a similar thing happens at 100°C when it takes 539 cal /g to change liquid water into a gas. This is called the latent heat of vaporization.

Answer 6

during any change of phase (solid to liquid in this example) the change occurs without external manifestation ie temperature does not change and it is called latent heat energy
