What else can I help you with?
Is this statement true or false Water vapor does not need a solid object on which to condense.?
True. Water vapor can condense directly into liquid water without needing a solid object as a surface for condensation to occur. The process of condensation can happen in the air when water vapor cools and reaches saturation point.
What two conditions need to exist in order to do work?
In order to do work, two conditions that need to exist are a force must be applied on an object and the object must move in the direction of the applied force. If either of these conditions is not met, work is not being done on the object.
What is difference between condensation and liquefaction?
Liquefaction is a change to a liquid from either a solid or a gas; whereas condensation is a change only from gas to liquid. Liquefaction takes place at very low temperatures(eg-Air is liquefied at -200degrees c) whereas condensation does not need such low temperatures, it occurs when water vapor changes to droplets of water on a glass of water taken out of a fridge.
Does condensation need heat?
Condensation releases energy rather than absorbing it, this is the latent heat of the change of state from liquid to gas and vice versa
Does condensation need heat energy?
Yes, condensation requires the removal of heat energy, as it is the process by which a gas changes to a liquid by losing heat. When water vapor in the air cools and loses energy, it condenses into liquid water droplets.
What is the carbon dioxide and water vapor in air called?
Condensation. In order for condensation to happen it would need something to stick on to such as soot, dirt, sand etc, this is called CONDENSATION NUCLEI. So basically our clouds are just a bunch of dirt suspended in the air.
What would Mars need in order to have condensation?
water
Does heat need to be taken away or added in order for cendensation to take place?
It needs to be added, in order for condensation to take place you have to have both cold and warm temperatures. For example, if you have ice water you usually have condensation because the ice and the air outside the glass mix and make condensation.
Why does photosynthesis need to happen?
photosynethesis needs to happen beacause in order for the animals and the humans to livewe need photosynthesis or this to happen.
What conditions are need for clouds to form?
1. Falling Temperatures 2. Water vapour in the air 3. Condensation nuclei-tiny particles of duct, soot, etc.
Which conditions must exist for condensation to occur in the atmosphere?
In order for water vapor to condense three things need to be present. The first is humidity, next is a temperature change (warm water vapor coming in contact with a cool surface), and finally there needs to be a condensation nuclei. A condensation nuclei is a solid on which condensation takes place such as a cold cup.
What lab equipment do you need for a desalination experiment?
You need a way to boil the water and allow the condensation to collect in a condensation coil that leads to a container holding the water

What special conditions do sheep need in order to survive?
Food, water, air and shelter.
What do reactions not need to make them happen?
Chemical reactions do not require the written authorization of any human agency, to make them happen. They also do not require a favorable alignment of the stars. They do not need psychotherapy or marriage counseling in order to happen. There are infinitely many other things that they do not need.
Why do the pipes in a steam heating system need to be insulated?
The pips in a steam heating system need to be insulated to prevent condensation. Condensation can lead to mold and or freezing of the steam pipes in the winter.
