The substance with the lowest known melting temperature is the noble gas helium.
Helium will not freeze at atmospheric pressures, but will freeze at about 1K (-272oC) when pressure is increased to 2.5 MPa (about 25 times atmospheric pressure).
Due to helium's small Atomic Mass, and relative insucceptibility to dispersion forces, it is unlikely that there is a substance with a lower melting temperature.

∙ 8y agoWater's melting point is when it changes from ice to water, at 32 degrees Fahrenheit. So, basically all metals would. For example, to melt steel it would be about 1800 degrees I believe.

When a substance melts the temperature of the substance?
it decreases.
Does a wet rock generally melts at a lower temperature than a dry rock true or false?
True, a wet rock melts at a lower temperature!
Which element melts at the lower temperature-oxygen or mercury?
oxygen
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
Which has a lower temperature ice water or ice?
Ice water has a lower temperature, but if you have plain water, and the ice water melts, it's likely that you'll have two glasses of water of the same temperature.
The temperature at which a substance freezes is lower than the temperature at which it melts?
Correct, the temperature at which a substance freezes is lower than the melting point.
When a substance melts The temperature of the substance increases?
it decreases.
When a substance melts the temperature of the substance?
it decreases.
What decreases the rate at which a substance melts?
decreasing the temperature
Does a wet rock generally melts at a lower temperature than a dry rock true or false?
True, a wet rock melts at a lower temperature!
What will happen if the ignition temperature is lower than the room temperature?
If the ignition temperature of a substance is lower than the room temperature where it is, then that substance ignites.
Which element melts at the lower temperature-oxygen or mercury?
oxygen
When does a substance changes from a solid to a liquid?
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
What is melting points degrees?
The temperature at which something melts, what that is depends on substance in question.
What happens to viscosity as temperature increases?
As the temperature rises, the viscosity, meaning a substance's resistance to flow decreases because a liquid based substance melts, and flows more.Viscosity decreases as temperature increases.
What is the movement of thermal energy from a substance at a high temperature to a substance at a lower temperature called?
Heat
When does a substance hit its melting point?
Different substances have different melting points. You'd need to specify the substance to learn the temperature at which that particular substance melts.
