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.
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 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 boiling point and melting point occur at the same temperature?
It depends on the substance and the pressure. For most substances at atmospheric pressure, the boiling point is much higher than the melting point. However, some things, like nitrogen and carbon dioxide, do not have any liquid phase at atmospheric pressure--they go directly from solid to gas and vice-versa.
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.
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 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.
The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
The conversation of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
What is the temperature where the vapor pressure of a liquid equals atmospheric pressure?
The boiling point of the liquid.
Why does the height of the column in a barometer changes as atmospheric pressure changes?
As the atmospheric pressure changes, the force pushing on the surface of the liquid changes. Therefore,the height of the liquid in the tube increases as the atmospheric pressure increases.
The melting point of a substance is its freezing point.?
No, the melting point of a substance is the temperature at which it changes from a solid to a liquid, whereas the freezing point is the temperature at which it changes from a liquid to a solid. These points are usually the same for a pure substance under normal atmospheric pressure.
