For most substances, it's the same temperature. For example, ice melts at 0°C (273K), and water freezes also at 0°C.
A few substances, such as agar, have a hysteresis. For example, agar melts at 85°C; to solidify it again, you have to cool it down to about 32-40°C.

∙ 9y agoYes, the temperature of a substance will vary while it is melting or freezing. Water will get cold when it freezes. Items that are melting heat up.
Wiki User
∙ 13y agoYes. A substance melts and freezes at the same temperature. Melting is as it changes from solid to liquid, freezing is from liquid to solid.
Wiki User
∙ 15y agoTemperature of a substance does not change when it in the process of freezing. Temperature will continue to decrease once the substance is completely frozen (solid).
Wiki User
∙ 9y agoWhen a substance is melting the temperature gets higher. This is because the molecules are beginning to spread out more and more.
Wiki User
∙ 13y agoThe more the substance, the longer and higher temperature it will take to melt/boil/freeze/condense.
Wiki User
∙ 11y agoIn theory, for the same substance they should be the equal. In actuality, there are slight variations. From a general chem class perspective however, the answer is yes.
Wiki User
∙ 11y agoNo, they are the same. It just depends on whether heat energy is being gained or lost.
Wiki User
∙ 13y agoIt remains constant.

When a substance is melting the temperature of the substance what?
it decreases.
Higher melting point than expected?
It is indeed possible for a substance to have a higher melting point than expected. This normally happens when the substance is impure.
The temperature at which a substance freezes is also its what?
The answer is that the temperature a substance freezes is also its melting point. Water freezes at 0 degrees Celsius into ice and if you heat ice up to 0 degrees Celsius it MELTS to give you water. Evaporation is the change from liquid to gas and condensation is the change from gas to liquid (for water this happens at 100 degrees Celsius).
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
The temperature at which a solid becomes a liquid is called the what?
Simply, the melting point. Think of an ice cube. The melting point is the temperature at which the ice cube MELTS into a liquid.
When a substance is melting the temperature of the substance what?
it decreases.
How can you determine if a substances is a solid at room temperature?
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
What kind of substance is a melting point?
what the heck are you asking? the melting point is not a substance. it's a temperature in which the substance starts to melt
What is the melting temperature of a substance?
This is the definition of the melting point of an element or substance. The melting point is when a solid begins to turn into a liquid. A substance also has a boiling point and freezing point.
What temperature at which a substance changes from solid to liquid is called its?
It is the boiling point of the substance.
What two factors determine if a substance will be a liquid?
The temperature of the environment and the melting and evaporation temperature of the substance.
How is the melting point of a substance defined?
= temperature at which (all of) a (pure) substance is melting: going from solid into liquid phase.
How is the melting point of substance defined?
= temperature at which (all of) a (pure) substance is melting: going from solid into liquid phase.
How is the melting point of a substance related to its melting point?
Both indicate the temperature at which the solid and liquid states of a substance are in equilibrium.
What is the temperature called at which a substance changes from a solid to a liquid?
It is the melting point of the substance.
If a substance is not at its melting or boiling point as the heat content of a sample of matter increases what happens?
As the heat content increases, the temperature of the substance will rise. However, if the substance is not at its melting or boiling point, it will not undergo a phase change. Instead, its temperature will continue to increase until it reaches its melting or boiling point, at which point a phase change will occur.
What is the melting point of Celsius?
Celsius is a measure of temperature not a substance, and therefore it has no melting point. What is the melting point of what material in Celsius? [You haven't named the substance you want the melting point of/for]
