Celsius is the same scale as Kelvin, except 0°C = 273.15°K, so 280°K = 6.85°C, and 320°K = 46.85°C.
If you live in the US, that's about 44°F and 116°F, respectively; now I don't know where the other answerer lives, but 46.8°C/116°F is a bit above room temperature to me, so I'd say the substance that melts at 280°K would be a liquid at room temperature, while the substance that melts at 320°K would still be quite solid.

Is cyclopentane a liquid or gas at room temperature?
Pentane is liquid at room temperature the melting and boiling point are respectively -130C and 36C. SOLID -130C-LIQUID-36C-GAS (left to right is phase change alternated respectively by melting and boiling normal temperature)
What does the melting point mean?
the highest temperature in which a solid substances turns into a liquid without any change in its chemical contents
is the melting point the temperature at which you given liquid changes to gas?
The melting point is the temperature at which a solid becomes a liquid.
Why is melting and freezing point of a substance same?
"Melting" and "freezing" are transition actions, going from solid-to-liquid form and liquid-to-solid form respectively. The point is the same transition temperature of that particular substance. The same goes for the transition temperature of the "boiling point" and "condensation point" of a substance.
What is melting points and the boiling points?
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
Is cyclopentane a liquid or gas at room temperature?
Pentane is liquid at room temperature the melting and boiling point are respectively -130C and 36C. SOLID -130C-LIQUID-36C-GAS (left to right is phase change alternated respectively by melting and boiling normal temperature)
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.
How does a substances melting point determine its state at room temperature?
If the melting point is under 20 oC the substance is a liquid.
What is the melting temperature of metal?
Melting temperature is the point where a substance is reduced to a liquid (this is the state it changes to). the usual melting point of substances is 100 degrees or higher.
What are some things that have melting points?
All substances have a melting point.Water, for example, has a melting point. It is simply the temperature at which a substance changes states to a liquid.
Do liquids have melting points?
No, they only have freezing points & gaseous points (it where the liquid becomes a gas). Why don' they have melting points? Well take this as an example: If you left your chocolate bar out in the sun it will melt and become a liquid. There for becoming a liquid IS melting, there is no further melting points to an object ounce it becomes a liquid. Substances have melting points. The melting point is the temperature at which a solid becomes a liquid, in other words, the temperature at which it melts.
The temperature at which a substance becomes a liquid?
It is different for different substances. the generic name for the temperature at which a solid becomes a liquid is the melting point. For a pure chemical compound or an element this is usually a sharp temperature rather than a range.
What temperature is argon liquid?
The melting point and boiling point of argon are 83.81 K and 87.302 K respectively. So argon is liquid in between these two temperatures.
What are some physical changes caused by changes in temperature?
it causes the 1. melting of solid substances 2. the solidification of liquid substances\ 3. the deformation of matter.
What does the melting point mean?
the highest temperature in which a solid substances turns into a liquid without any change in its chemical contents
How is boiling point and melting point related?
Boiling points and melting points are temperatures at which change of phase occurs to liquids andsolids. Some substances, such as water, have a TRIPLE POINT temperature at which all three phases (solid, liquid, vapor), exist simultaneously.Boiling point of a liquid is the temperature at which its phase changes into vapor and the melting point of a solid is the temperature at which it changes state from solid to liquid. The solid and liquid phase of a substance exist in equilibrium at the melting point. The reverse change from liquid to solid is referred to as the freezing point. The freezing point of a substance is often determined by observing the temperature at which a solid begins to change into a liquid, which is actually the melting point, because a characteristic property of some substances is their ability to supercool.
When solid changes into liquid?
Solids changing to liquids are melting Liquids changing to solids are freezing Solids changing to gas are subliming Liquids changing to gas are boiling Gases changing to liquids are condensing.
