Melting point. That depends entirely on the substance. Different things liquefy at different temperatures.

What kind of change is involved when you change solid water into liquid water?
Changing a substance from solid into a liquid is called a change of state or a change of phase. Melting is the name given to the change of state from a solid to a liquid.
Is temperature an element?
No, temperature is the amount of thermal energy in a given amount of a substance.
At room temperature a substance with a melting point of 40 Celsius is a?
Room temperature is 25 oC so it would still be a solid. It would be 104 degrees F... So. unless the substance's boiling point is below that, it would be a solid. otherwise it would be a gas.
What name is given to the temperature at which a gas turns into a liquid?
It is actually Boiling point
What does melting point mean in science terms?
The temperature at which a solid, given sufficient heat, becomes a liquid. For a given substance, the melting point of its solid form is the same as the freezing point of its liquid form, and depends on such factors as the purity of the substance and the surrounding pressure. The melting point of ice at a pressure of one atmosphere is 0°C (32°F); that of iron is 1,535°C (2,795°F). See alsostate of matter.
The temperature at which a given substance will change from a liquid into a gas?
The temperature in which a given substance will change from a liquid to a gas is its boiling point. Every element, compound and mixture has a different boiling point. Use an SI data book or the internet to find the boiling point of a particular suubstance.
What substance become a liquid when his temperature is above 0 degrees Celsius?
Any substance with a melting point above this given temperature.
What is the heat of evaporation?
Heat of vaporisation is the amount of heat require to transform substance from liquid to gas state at constant temperature. Heat of vaporisation expressed in kJ/kg of substance.
What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
What is the name given to the change in state from gas to liquid?
When a substance is liquid and it changes to gas, we call that boiling.
What kind of change is involved when you change solid water into liquid water?
Changing a substance from solid into a liquid is called a change of state or a change of phase. Melting is the name given to the change of state from a solid to a liquid.
How is elements related to physical change?
Well, if you were for example discussing the the physical change of substance from one state to another, eg. Ice to liquid water than the relation to physics concerns energy. When discussing temperature change what you are in reality dealing with is how much energy a given substance or object contains.
How do you know that particles in a gas have more energy than particles of same substance as a liquid or a solid?
We know that for any given substance, and at a given pressure, the gas phase exists at a higher temperature than the liquid phase, which exists at a higher temperature than the solid phase. And temperature measures heat energy per molecule or atom, hence, gas particles have more energy than particles of the same substance in their liquid or solid phase.
Why are the melting point and boiling point of the same matter different?
Boiling point is the temperature at which a substance turns into a gas, while melting point is the temperature at which a substance turns into a liquid state from a solid state. The boiling point is always a higher temperature then the melting point. The melting point has a substance turn into a liquid from solid, and boiling point has a liquid turn into a gas.
Boiling liquid maintains a constant temperature because?
The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.
When does evaporation occurs for a given substance?
Evaporation is the phenomenon of transformation from liquid to gas which occur at the surface of the liquid. Evaporation is possible also at a temperature lower than the boiling point.
How do you find a mass of a substance dissolved in a solution given temperature and joules?
You can find the mass of a substance dissolved in a solution given temperature and joules using the relation q=mc(change in T). Where q is heat in joules, m is the mass, c is the specific heat capacity, and T is the temperature.
