What is the relationship between the rate of evaporation and the rate of condensation of the vapor of a liquid in a closed container and has a constant vapor pressure?
In a system at constant vapor pressure, a dynamic equilibrium exists between the vapor and the liquid. The system is in equilibrium because the rate of evaporation of liquid equals the rate of condensation of vapor. -KarkatHorns
How does a water pot boiler work to heat water efficiently?
A water pot boiler works by heating water in a closed container using a heat source such as a stove or electric element. The heat causes the water to boil and turn into steam, which then rises and transfers heat to the surrounding water. This process efficiently heats the water in the pot.
What is a closed metal container containing hot water or steam?
A closed metal container containing hot water or steam is typically called a boiler. Boilers are used to generate heating or process steam for various industrial or residential applications. They operate by heating water to produce steam, which is then circulated for heating or mechanical power.
Why is it important to keep liquids like petrol and methylated spirit in close containers?
It is important to keep liquids like petrol and methylated spirit in closed containers to prevent evaporation, reduce the risk of spills, and minimize the possibility of accidental ingestion or contact with skin. Closed containers also help to maintain the integrity and quality of the liquids by preventing contamination.
How do you calculate the amount of gas required to raise the pressure of a closed vessel to a known value?
If you know the temperature, pressure and volume of the vessel, you can calculate the amount of moles through the Ideal gas law. PV = nRT That is assuming you have ideal conditions. If not, a variance of the ideal gas law can be used in order to get the moles of your gas.
How does boiler capacity is determine?
In boiler which is a closed vessel fluids are heated & stored for use in different processes
Can evaporation occur in a closed container?
Yes, evaporation can still occur in a closed container, but the rate of evaporation will eventually slow down because the amount of water vapor in the container will reach an equilibrium with the liquid water. At this point, the rate of condensation will equal the rate of evaporation.
What is Effect of relative humidity on water evaporation?
humidity effects the evaporation in the following ways: 1. In a closed container rate of evaporation will have a lesser value than usual.but there will be no decrease in the rate.
How does evaporation in a closed container differ from evaporation in an open container?
In a closed container, the water vapor cannot escape into the surrounding air, so the rate of evaporation decreases as the space becomes saturated. In an open container, the water vapor can escape into the surrounding air, allowing for continuous evaporation as long as there is a difference in vapor pressure between the liquid and the air.
When pilot light goes out on a boiler is gas escaping?
No. The pilot valve is closed when no flame is sensed by the thermocouple.
Is boiler a closed system?
A boiler can be a closed system if you include the pipes it is connected to, but usually there are relief valves that will allow the escape of steam to protect against excess pressure and inlets that will allow adding liquid to the boiler to make up for fluid lost from the pressure valves. Also most boilers are imperfectly sealed so they leak a little bit. If you do not consider the attached piping, then a boiler would not be considered a closed system since it would be constantly sending out steam and receiving condensate in return.
Can evaporation of water take place in a closed room without a fan?
Yes. Until the humidity reaches 100 %.
How can I calculate water pressure in a closed system?
To calculate water pressure in a closed system, you can use the formula: Pressure Force/Area. This means that pressure is equal to the force exerted on the water divided by the area over which the force is applied. By knowing the force and the area, you can calculate the water pressure in the closed system.
What is a boiler backfire?
Damper is not operating according to flame (high/low) OR Diesel accumulated in Combustion chamber /Ehaust damper may be closed
Is a boiler an internal combustion engine?
No, a boiler is not an internal combustion engine. A boiler is a closed vessel that uses heat to generate steam or hot water for heating or power. Internal combustion engines, on the other hand, are machines that generate power by burning fuel within a combustion chamber.
What does alcohol increases especially if the eyes are closed?
euphoria
What happens to molecules with sufficient energy when a liquid is placed in a closed container?
When a liquid is placed in a closed container, molecules with sufficient energy can escape from the liquid and turn into gas. This process is called evaporation.
