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.

Does boiling point and melting point occur at the same temperature?
No, boiling point and melting point occur at different temperatures. The melting point is the temperature at which a substance changes from a solid to a liquid, while the boiling point is the temperature at which a substance changes from a liquid to a gas.
Melting point and boiling point of Garnet?
The melting point of garnet is approximately 2,000°C (3,632°F), while the boiling point is not defined as garnet undergoes decomposition before it reaches a boiling point.
Why is the boiling point more sensitive to pressure than the melting point?
Boiling point is more sensitive to pressure changes because it involves overcoming intermolecular forces to change from a liquid to a gas, which is highly dependent on pressure. In contrast, melting point primarily involves the organization of particles in the solid phase, which is less affected by pressure changes.
How does elevation affect the melting point of a compound?
As elevation increases, atmospheric pressure decreases. This leads to a decrease in the boiling point of a compound because lower pressure means molecules can escape more easily. However, elevation generally has a minimal effect on the melting point of a compound.
What is the relationship of boiling point with atmospheric pressure?
The boiling point of a substance decreases as the atmospheric pressure decreases. This is because lower atmospheric pressure reduces the pressure pushing down on the liquid, making it easier for the liquid to vaporize. Conversely, higher atmospheric pressure increases the boiling point of a substance as more pressure is needed to overcome the atmospheric pressure and cause the liquid to vaporize.
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.
How does atmospheric pressure affect the melting point of a liquid?
I assume you mean melting point of a solid (if it's liquid it has already melted). It decreases as you increase the pressure.
What state of matter is calcium in at atmospheric pressure?
Calcium is a solid at atmospheric presure up to the melting point of 842 0C.
Determination of melting pont of ice and the boiling point of water?
The melting point of ice is 0°C (32°F) at standard atmospheric pressure. The boiling point of water is 100°C (212°F) at standard atmospheric pressure.
What is melting point of iron?
The melting point of iron is recorded to be around 2,800 degrees F. This converts to 1,538 degrees C. These melting points are at atmospheric pressure.
How cold does water have to be to freeze in kelvins?
It depends on the pressure. At normal atmospheric pressure, the melting point of water is about 273.15 K.
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.
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).
If you performed a melting point experiment in the laboratory and on the top of the mountain would your results differ explain?
Yes, the results could differ because the atmospheric pressure varies with altitude, which can affect the boiling point of liquids, including the melting point of solids. The lower atmospheric pressure at the top of a mountain can cause the melting point of a substance to be slightly lower than at sea level.
What is the melting point of the oxygen?
The melting point of oxygen is -218.79 degrees Celsius.
Does boiling point and melting point occur at the same temperature?
No, boiling point and melting point occur at different temperatures. The melting point is the temperature at which a substance changes from a solid to a liquid, while the boiling point is the temperature at which a substance changes from a liquid to a gas.
What is true about the melting point and freezing point of water?
The melting point and freezing point of water is the same at 0 degrees Celsius (32 degrees Fahrenheit) under standard atmospheric pressure. This means that water will transition from solid to liquid (melting) or liquid to solid (freezing) at this temperature.
