Why does water vapor condenses in the condenser tube?

The water vapor molecules transfer energy to the colder air. This makes the water vapor molecules move more slowly. Their attractions overcome their motion and they join together or condense to form liquid water.

What will happen to the condensed vapor in the water condenser?

The process in which water vapor turns into a liquid is called condensation. The gaseous water molecules release energy into the cooler air around them and move closer together. The spaces between the molecules decrease until they are close enough to change from a gas to a liquid.

What is required for evaporation and condensation?

All matter is made of tiny moving particles called molecules. Evaporation and condensation happen when these molecules gain or lose energy. This energy exists in the form of heat.

At what temperature does water evaporate and condense?

For temperature above 0 Kelvin and 273.15 Kelvin (0 Celsius) or below then water condensing from the atmosphere would form ice. For temperature between 0 Celsius and 100 Celsius liquid water would condense. Above 100 Celsius water wouldn’t condense unless the gas phase of the system was under pressure.

Why does water vapor condense in the condenser tube quizlet?

The purpose of a condenser coil is to reject unwanted heat from a refrigeration or air conditioning system. It does this by condensing the high pressure, high temperature gas to a liquid. After all the vapor is condensed to liquid, the liquid is subcooled in the last portion of the condenser.

How much condenser sub cooling should the condenser coil have on a air cooled condenser with a Txv metering device at design temperatures?

Subcooling on systems that use a thermostatic expansion valve (TXV) should be approximately 10F to 18F.

How does water condense?

Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.

How can you cause water to condense?

Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.

How does condensation occur in the water cycle?

Condensation is the process by which water vapor in the air is changed into liquid water. These clouds may produce precipitation, which is the primary route for water to return to the Earth’s surface within the water cycle. Condensation is the opposite of evaporation.

Can water be condensed?

The answer is yes, You can compress water, or almost any material. However, it requires a great deal of pressure to accomplish a little compression. The water at the bottom of the ocean is compressed by the weight of the water above it all the way to the surface, and is more dense than the water at the surface.

How much heat must a condenser dissipate?

Air cooled condensers normally requires between 125°F to 130°F condensing temperature to reject heat to a 100° ambient, while a water cooled condenser can operate at 105°F condensing temperature and reject its heat to a 95°F water stream.
