The greater the pressure acted upon the substance,the melting point of the substance lowers. For example, a copper wire is tied around a block of ice. It is noticed that the area around the tied place melts faster than the other parts of the ice. This implies that a greater pressure is acting upon the tied area of the block of ice. -KAREEM IBRAHIM.

What are the effects of pressure on melting boiling points of a substance?

Increasing pressure generally increases the melting and boiling points of a substance. This is because pressure forces molecules to be packed closer together, making it harder for them to break free from each other in the solid or liquid phase. Conversely, decreasing pressure lowers the melting and boiling points.


Would an increase in pressure cause this substance to freeze or melt?

Corrected: Only with some peculiarsubstances like ice contract on melting and expand on freezing. Since pressure also contracts ice, doing the same work of melting, the melting point of ice DECREASES with INCREASE of pressure.Added:In 'Related links' attached to this page (lower left corner) a diagram-picture of"Melting point: Temperature and Pressure" is shown asGreen line for most 'normal' solidsand ofWater-Ice: it is the Green-Dotted line.


Are freezing and melting points characteristic properties?

Yes, freezing and melting points are characteristic properties of a substance. They are specific temperatures at which a substance changes its state from solid to liquid (melting) or from liquid to solid (freezing) under normal atmospheric pressure.


What is the temperature called at which a substance changes from a solid to a liquid?

The temperature at which a substance changes from a solid to a liquid is called the melting point.


What is the melting pattern of the substance under study?

The melting pattern of the substance under study refers to the specific temperature range at which the substance changes from a solid to a liquid state.

Does melting point depend on atmospheric pressure?

Yes, the melting point of a substance can be influenced by atmospheric pressure. In general, an increase in pressure raises the melting point of a substance, while a decrease in pressure lowers it. This is because pressure affects the equilibrium between the solid and liquid phases.


For any pure substance the boiling point and melting point will always remain?

The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.


What processes is most affected by pressure freezing or boiling or melting?

Boiling and freezing points of a substance are affected by pressure. An increase in pressure raises the boiling point and lowers the freezing point of a substance. Melting point is not significantly affected by pressure.


What is the temperature and pressure at which a solid becomes a liquid?

Varies between substances. Ex The vaporization pressure and temperature of water is different from mercury.ans2. The concept you should study is the Triple Point of the material. The temperature and pressure at which the material can co-exist as liquid, solid, and gas phases.For water, this temperature is 273.16oK at 0.6117 kPa. (and has been so for 50 years, but 0oC is adequate for ordinary mortals.)For CO2 the TP is at 216.55oK at 517kPa.For mercury, TP is at 23.2oK, at 1.65x10-7 kPa.


What temperature will a substance melt if the atmospheric pressure is 1.2?

Leaving aside the obvious deficiencies in the question (1.2 WHAT? What substance?)... For most substances pressure has only a tiny effect on the melting point, and enormous pressures are required to change the melting point significantly (in contrast to boiling point, where pressure has a relatively much greater effect).


What are the effects of pressure on melting boiling points of a substance?

Increasing pressure generally increases the melting and boiling points of a substance. This is because pressure forces molecules to be packed closer together, making it harder for them to break free from each other in the solid or liquid phase. Conversely, decreasing pressure lowers the melting and boiling points.


What is the health benefit of melting metal?

Any relation between some health benefits and melting of metals.


Physical state when a substance is melting?

When a substance is melting, there is equilibrium between the solid and liquid state, meaning it is both a solid and a liquid.


Does melting point change from altitude to altitude?

Yes, the melting point of a substance can change with altitude due to the variation in atmospheric pressure. As altitude increases, atmospheric pressure decreases, which can affect the boiling and melting points of substances. Generally, lower pressure at higher altitudes can result in lower melting points for many substances.


What is the normal melting point?

The normal melting point is the temperature at which a substance changes from a solid to a liquid at standard atmospheric pressure (1 atm). The normal melting point is a characteristic physical property of a substance and can vary depending on the specific material.


Why is there a pattern between melting point and atomic radius?

A relation doesn't exist.


What is high melting point?

The melting point of a solid is the temperature at which it changes STATE from SOLID to LIQUID. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends (usually slightly) on pressure and is usually specified at STANDARDatmospheric pressure.
