The extra heat supplied is used in the melting of ice which is called the latent heat of fusion. Similarly, when a liquid starts boiling the temperature of the liquid does not change instead of a continuous supply of heat. ... That's why the temperature of a substance remains constant during its melting or boiling..

Keep it Airtight For extra security, place a layer of plastic wrap between your ice cream and the lid. Air is also responsible for freezer burn, which desiccates and crystalizes the surface of ice cream. A tight lid helps, but air trapped inside the container over long periods will also do damage.

In its pure state, water freezes at 0°C or 32°F. By using salt, that freezing point can be lowered which forces the ice to melt and prevents the water from freezing or re-freezing. ... As salt touches this water, it starts to dissolve – subsequently lowering the freezing point and melting the ice surrounding it.

Once the oven has finished its cleaning cycle, let it cool down, then give it a rinse. Let it dry, then fire it up. You should hopefully not smell any plastic residue. The oven should be safe to use..

Answer: The 'temperature of a substance' remains constant during its melting and boiling point because the change in any state of matter as n solid to liquid or the liquid to a gas involves crossing the 'latent heat of fusion' which causes a change in the intermolecular spacing of the molecules in the substance.
