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.
What 2 factors affect the boiling point of water?
Pressure & Temperature :) Apex
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.
Why is atmospheric pressure greater at sea?
Atmospheric pressure is the weight of the air above the point... at sea level there is more air above the point then there would be at 10,000ft
Is there a relationship between the concentration of a solution in a saturation point of a salute?
Yes, there is a direct relationship between the concentration of a solution and its saturation point. The saturation point is the maximum concentration of a solute that can dissolve in a solvent at a given temperature and pressure. When a solution reaches this point, any additional solute will not dissolve and will remain undissolved. Factors like temperature and pressure can affect the saturation concentration, as higher temperatures often increase solubility.

Which factor causes atmospheric pressure?
Atmospheric pressure is primarily caused by the weight of air above a specific point on the Earth's surface. Gravity pulls air molecules towards the Earth, creating a force that results in atmospheric pressure.
Does gauge pressure include atmospheric pressure?
Yes, gauge pressure includes atmospheric pressure. Gauge pressure is the pressure measured above atmospheric pressure, so it accounts for the atmospheric pressure as a reference point.
How does the boiling point different from lowland and highland?
The boiling point of a substance is lower at higher altitudes due to lower atmospheric pressure, which reduces the pressure exerted on the liquid. In contrast, at low altitudes with higher atmospheric pressure, the boiling point is higher as more pressure is needed to overcome atmospheric pressure.

What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
How does atmospheric pressure affect the boiling point of matter?
Atmospheric pressure exerts pressure on the molecules of the liquid, confining them. In order to boil, the electrons must be excited, but must become hotter to overcome the pressure of the atmosphere. Therefore, pressure makes a liquid boil at a higher temperature. With a solid, the molecules are already compact together and have to be melted before they can be boiled. This does not require excitation of electrons, but it does require movement of electrons. Once the solid is melted, pressure will make it harder for the electrons to become excited.

What factor besides the temperature affects the boiling point of water?
Air pressure also affects the boiling point of water. The higher the air pressure, the higher the boiling point.
What is the name for pressure caused by the weight of the atmosphere?
Simply put, atmospheric pressure is the force exerted on a measuring point by the weight of the air molecules on top of that point. Standard atmospheric pressure, measured at sea level at 59F or 15C, is used as a reference point and is equal to 29.92 inches of mercury or 1013 millibars of pressure.
What is the physical state of argon at -197 and normal atmospheric pressure?
Argon will be a gas at -197°C and normal atmospheric pressure, as it has a boiling point of -185.8°C at atmospheric pressure.
