Can you please-Compare the melting points of substances that are gases at room temperature with solids and liquids?
Substances that are gases at room temperature typically have lower melting points than solids and liquids because their intermolecular forces are weaker. Gases have molecules that are further apart, making it easier to overcome these weak forces to change their state. Solids and liquids have stronger intermolecular forces that require more energy to break, resulting in higher melting points.
What else can I help you with?
Do liquids have melting points?
NO!!! However, on change of physical state;- solid to liquid it is 'melting' liquid to solid it is 'freezing' Similarly liquid to gas it is evaporation/boiling gas to liquid it is condensation. Different substances have different temperature for change of physical state. Water being the scientific standard has; - melting/freezing at 0oC boiling/evaporation at 100oC
Do all liquids have the same boiling and melting point?
No, different liquids have different boiling and melting points depending on their chemical composition. The boiling point is the temperature at which a liquid turns into a gas, while the melting point is the temperature at which a solid turns into a liquid. Each liquid has its own unique set of physical properties that determine its specific boiling and melting points.
What is the melting temperature of metal?
The melting temperature of metal varies depending on the specific type of metal. For example, the melting temperature of iron is around 1,538 degrees Celsius, while the melting temperature of aluminum is around 660 degrees Celsius.
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.
Why can the boiling point and the melting point be used to help identify a substance?
The boiling and melting points are almost unique to individual substances. If it should happen that two possible substances have the same melting point, they can still be identified by the method of mixed melting points. If substances A and B have the same melting point and you mix them, the mixture will melt belowthe tabulated temperature. Thus if you mix your unknown with a sample of what you think it is, if you are right it will still melt sharply at the expected temperature, but if you are wrong it will melt gradually and at a lower temperature.
What temperature do liquids turns into solids?
That temperature is known as the melting point. It is different for every substances.
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.
Do liquids have melting points?
NO!!! However, on change of physical state;- solid to liquid it is 'melting' liquid to solid it is 'freezing' Similarly liquid to gas it is evaporation/boiling gas to liquid it is condensation. Different substances have different temperature for change of physical state. Water being the scientific standard has; - melting/freezing at 0oC boiling/evaporation at 100oC
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.
Do all liquids have the same boiling and melting point?
No, different liquids have different boiling and melting points depending on their chemical composition. The boiling point is the temperature at which a liquid turns into a gas, while the melting point is the temperature at which a solid turns into a liquid. Each liquid has its own unique set of physical properties that determine its specific boiling and melting points.
What are 5 liquids that do not have water?
-- pure alcohol at room temperature -- mercury at room temperature -- oxygen below its boiling temperature -- iron above its melting temperature -- nitrogen below its boiling temperature -- salt above its melting temperature -- gold above its melting temperature -- any other element or compound that is not H2O, above its melting temperature and below its boiling temperature
What characteristics do ionic liquids have?
Such liquids have high density, good electrical conductivity and become solid as temperature decreases from their melting point.
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.
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?
The melting temperature of metal varies depending on the specific type of metal. For example, the melting temperature of iron is around 1,538 degrees Celsius, while the melting temperature of aluminum is around 660 degrees Celsius.
What is the substances melting point the same as?
A substance's melting point is the temperature at which it changes from a solid to a liquid state. It is unique to each substance and does not necessarily match the melting point of any other substance.
What becomes a solid above the melting point?
The melting point is the temperature which a material, element or mixture, changes from the solid to a liquid. Therefore, all liquids become solids above the melting point.
