If the boiling point is recorded when the liquid enters the capillary tube will it be recorded too high or too low?
If the boiling point is recorded when the liquid enters the capillary tube, it will likely be recorded too low. This is because the liquid may not have reached its true boiling point yet, as the temperature can drop briefly upon entering the narrower environment of the capillary tube. Additionally, any heat loss during this transition can further contribute to an inaccurately low boiling point measurement.

If the boiling point is recorded when the liquid enters the capillary debater the heat is removed) will it be recorded too high or too low?
If the boiling point is recorded when the liquid enters the capillary and heat is removed, it will likely be recorded too low. This is because the removal of heat can cause the liquid to cool slightly before it reaches the actual boiling point. Consequently, the observed boiling point will not accurately reflect the true boiling point of the liquid under standard conditions.
Which boils quicker liquid with high boiling point or liquid with low boiling point?
A liquid with a lower boiling point will boil quicker because it requires less energy to reach its boiling point compared to a liquid with a higher boiling point.
What is vaporization at the surface of a liquid that is not boiling?
Vaporization at the surface of a liquid that is not boiling is called evaporation. It is a process in which molecules of a liquid escape into the gas phase without the liquid reaching its boiling point. Evaporation occurs at temperatures below the boiling point of the liquid.
What happens to the boiling point of a liquid solvent when a solid or liquid is dissolved in that liquid?
The boiling point is usually increased.
How is polarity related to capillary attraction?
Because of the polarity of water, it exhibits a greater cohesion and adhesion to itself and other substances. This means that water holds on to itself more firmly than it does other substances.

If the boiling point is recorded when the liquid enters the capillary and heat is removed, it will likely be recorded too low. This is because the removal of heat can cause the liquid to cool slightly before it reaches the actual boiling point. Consequently, the observed boiling point will not accurately reflect the true boiling point of the liquid under standard conditions.
Briefly describe two methods or techniques for the determination of boiling point?
Distillation - where the constant tempreature of the vapor given off when boiling the liquid at the lowest temperature possible is recorded as the boiling point. Capillary Bell - where the temperature, under pressure, that the liquid enters the bell in place of the vapor is recorded as the boiling point of the liquid.
When should boiling point be recorded?
When the liquid is boiling steadily and the temperature has stabilised.
When should the boiling point of a liquid be recorded?
The boiling point of a liquid should be recorded when the liquid reaches a constant temperature at which it changes from a liquid to a gas (vapor) under a specific pressure. This usually occurs when the vapor pressure of the liquid equals the atmospheric pressure.
Derive an expression for expression for rise of liquid in a capillary tube?
deduce an expression for height of a liquid in capillary tube. also write practical applications of capillary action.
What is the purpose of the short length of broken capillary tube used in the determination of boiling point?
The short length of the broken capillary tube in boiling point determination serves to ensure that the liquid inside is exposed to both the heat source and the atmospheric pressure effectively. This design allows for a quicker response to temperature changes, enabling the observer to better detect the moment when the liquid begins to boil. Additionally, the short length minimizes the risk of liquid being trapped, which could lead to inaccurate readings. Overall, it aids in achieving a precise measurement of the boiling point.
The height of a liquid in a capillary tube is not dependent on?
the height of a capillary tube is not dependent on
What is the working principle of a condenser?
A condenser rejects heat to the environment to turn vapor into liquid. Ideally a vapor enters the condenser as saturated vapor, meaning it's at the boiling point. The vapor condenses and leaves the condenser at saturated liquid (also at the boiling temperature).

Why does liquid rise in a capillary tube?
Liquid rises in a capillary tube due to capillary action, which is the result of adhesive and cohesive forces between the liquid and the tube. Adhesive forces between the liquid and the tube's surface cause the liquid to be attracted to the tube, while cohesive forces within the liquid molecules help pull the liquid up the tube against gravity.
Which boils quicker liquid with high boiling point or liquid with low boiling point?
A liquid with a lower boiling point will boil quicker because it requires less energy to reach its boiling point compared to a liquid with a higher boiling point.
Name of liquid used in capillary thermostats?
You want a liquid that is not compressible so polar compounds are preferres. For safety, the nontoxic and highly stable silicones are used. They have low vapor pressures and high boiling points so they remain liquid and are quite noncompressible. This type of thermostat is filled with Alcohol, which responds well to changes in airconditioned space.
