it decreases.
What else can I help you with?
The phase of matter can be changed by?
changing the temperature or surrounding pressure of a substance
What substance melts at a lower temperature?
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.
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.
What is a substance that melts at room temperature described as?
A substance that melts at room temperature is described as a "melting point" material, typically classified as a solid that transitions to a liquid state at temperatures around 20-25 degrees Celsius (68-77 degrees Fahrenheit). Examples include certain fatty acids and some waxes. These substances can exhibit unique properties, such as being malleable or pliable when in their liquid form.
At room temeperature a substance with a melting point of 40 degrees celsius is?
know you then, only one substance 40 degress celsius melts, yes?
When a substance melts The temperature of the substance increases?
it decreases.
What decreases the rate at which a substance melts?
decreasing the temperature
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 solid substance never melts?
No solid substance exists that never melts. All substances have a melting point at which they transition from a solid to a liquid state due to changes in temperature.
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.
What causes phase changes?
If a certain substance has reached a temperature at which it either melts, freezes, evaporates, ect.
Are the melting and freezing of a substance the same?
Yes. A substance melts and freezes at the same temperature. Melting is as it changes from solid to liquid, freezing is from liquid to solid.
What is the melting point temperature?
The temperature at which the solid melts, which remains constant until all of the substance is melted.
When a substance is heated its temperature increases. What other change might be observed?
Ordinarily when a substance is heated it expands. In some cases it melts. In some cases it vaporizes/evaporates.
Does melting lose or gain temperaturre?
loses When ice melts it gains heat. The environment, however, loses heat. So what does heat have to do with temperature? Often they vary in the same direction; temperature has been likened to the average kinetic energy of the substance. Melting typically ( e,g,, for ice-water) clamps the temperature at a constant value, but heat flows into the substance that melts.
What is an Melting point?
An atom itself does not melt. The substance made out of atoms melts when it gets to hot in temperature, and the increased energy in the atoms causes the substance to fall apart somewhat.
