What causes steam to condense?

When the water was heated, its molecules began to move rapidly, turning some into its gas phase: steam. Without heat, the water molecules inside the bottle start condensing—that is, they start turning from steam back into liquid water.

What happened when steam is condensed?

When liquid water solidifies it becomes ice.

What happens to steam and moisture when it cools down?

When the water vapor cools enough, the attractions between the molecules bring them together. This causes the water vapor to change state and become tiny drops of liquid water. The process of changing from a gas to a liquid is called condensation.

Why is steam less dense than water?

Considering the molecular arrangement of liquids and vapours, it is logical that the density of steam is much less than that of water, because the steam molecules are further apart from one another. The space immediately above the water surface thus becomes filled with less dense steam molecules.

How is steam condensed in a condenser?

The fuel is fired in a boiler which converts the heat released from combustion to steam at high pressure and temperature. This steam is then expanded through a turbine for generation of electrical power. Exhaust steam from the turbine is condensed in a heat exchanger and then returned via the feed pumps to the boiler.

What does steam condense mean?

Condensate is the liquid formed when steam passes from the vapor to the liquid state. In a heating process, condensate is the result of steam transferring a portion of its heat energy, known as latent heat, to the product, line, or equipment being heated.

When ice is heated what happens when steam is condensed?

When ice is heated, it changes to water and water on further heating gets converted to steam. What happens when steam is condensed? When steam is condensed, again liquid water is formed. This process involves change of state that is gaseous phase changes to liquid phase and no new substance is formed.

Which is heavier air or steam?

Which is Heavier, Air or Steam? The average molecular weight of air is 29, which means that 1 mole weighs 29 grams. The molecular weight of steam (water) is 18, which means that 1 mole weighs 18 grams.

How much energy does it take to condense steam?

Water vapor (steam) is releasing about 2,260 kJ/kg when condensing into liquid water at 100°C. The water specific heat is 4182 J/(°C kg). If 1 kg of water vapor at 100°C is cooled down to 20°C then it releases 2,260,000 + 80*4,182 = 2,594,560 J of energy.

What is the white smoke coming out of the Kettle?

At first you don’t see anything; that’s the steam. And then after the steam are the small white billows of smoke, which is actually the steam condensing back into water vapor (due to contact with the air). In other words, the water inside the tea kettle boils, evaporates in the form of bubbles and comes out of the spout as steam.

What is the difference between smoke and steam?

That smoke is not actually steam but rather vapor (though most people would claim it is steam). Steam is an invisible gas, unlike water vapor, which appears as a mist or fog.

Why is there no steam coming out of my radiator vent?

So if you have no heat on an upper floor in your home and it’s steam heat the most likely the radiator steam vent or vents are not working on the radiator valves are closed. Anon if burner is operating but the boiler is not producing steam TURN IT OFF and call for service – the system may be unsafe, out of water, and risking boiler damage too.

Why is there condensate coming out of my radiator?

That’s because condensate, produced by cooling steam in the radiator, has to be able to drain back out of the radiator.
