What is the temperature at a substance changes from solid to liquid?

Answer 1

Depends on the substance.

The things that increase the melting point are the intermolecular forces and the size of the molecule.

Water is a liquid at room temperature because of the hydrogen bonds (strong) it can form with other water molecules.

It turns from liquid to solid at 0 oC.

But there are also substances that have the same size as water but are gasses at room temperature, for example methane.

Methane has a melting point of -182 oC, eventhough it is about the same size as water.

This is because methane is lacking those hydrogen bonds, making the intermolecular forces alot smaller.

Other molecular forces are van-der-waals forces and dipole-dipole interactions.

Answer 2

The temperature remains constant during the phase change from solid to liquid. This is known as the melting point of the substance. The energy supplied is used to overcome the forces holding the particles together, rather than increase the temperature.

Answer 3

That would be the substances melting point, Since you do not name the substance I can`t give you a temperature.

Answer 4

32 degrees Fahrenheit for water - otherwise it depends on the liquid or solid

Answer 5

It varies completely with the substance. Water, about 32 degrees, butter, about 82 degrees, lead, about 650 degrees, etc.

Answer 6

This temperature is called freezing point and is different for each substance and material.

Answer 7

The freezing point is when a liquid changes into a solid.

Answer 8

freezing point

Answer 9

Freezing Point.

Answer 10

This is the melting point.
