Would something freeze and melt at the same temperature?

Answer 1

This is a strange question. Water boils usually at 100 degrees Celsius and freezes at 0 degrees Celsius. Who understands this question? I think you mean "If a substance changes from solid to liquid when the temperature exceeds 100 degrees, will it change from liquid back to solid when cooled to below 100?" Yes, it will.

Answer 2

No, freezing and melting refer to opposite processes. Freezing is when a substance changes from a liquid to a solid state, while melting is when it changes from a solid to a liquid state. These processes occur at specific temperatures, but a substance cannot be freezing and melting at the same time.

Answer 3

Yes. However freezing and melting occur at different energy levels. Water both freezes and melts at 32 degrees Fahrenheit or 0 degrees Centigrade. However, a gram of water must release 80 calories of energy (A calorie, not a food calorie which is 1000 real calories, is that amount of energy necessary to heat one gram of water 1 degree centigrade), in order to freeze, and a gram of ice must absorb 80 calories in order to melt.

If ice is floating in water and assuming the ice is neither melting, or increasing in size, then the temperature must be the freezing point.

A question on one of my high school physics tests in 1967 began "A beaker of ice and water have been sitting on a desk for 10 minutes" . I was unable to answer the question because I needed to know the temperature of the water. Cleverly, my teacher was trying to find out if I knew that water and ice can only co-exist in water at the freezing point.

Answer 4

No. A solid is simply a substance that is at a temperature lower than its freezing point. Gallium, which is solid at room temperature has a melting/freezing point of 30 degrees Celsius while Tungsten, also solid at room temperature has a melting/freezing point of 3422 degrees Celsius.

Answer 5

Yes, the freezing point and melting point of a substance are the same temperature. The link on Enthalpy of Fusion will help explain why the temperatures are the same.

Answer 6

yes it is true. Melting point and Freezing point are same temperatures

Answer 7

Yes, yes it does. With water both freezing point and melting point are 0 degrees Celsius

Answer 8

Anything dissolved in it, pressure that is higher or lower than normal.

Answer 9

yes it melts at 0 degrees Celsius

Answer 10

no
