If a substance undergoes a phase change what happens?
When a substance undergoes a phase change the molecules either order themselves or disperse themselves randomly. In a solid the molecules are unable to freely move in space. In liquid form they are able to move around in the space they occupy and in gas form they can move freely in any open area. In gas state the molecules will have more kinetic energy than liquid or solid, and liquid more than solid.
What happens to energy when a liquid turns into gas?
When a substance is changing from liquid to gas, the energy, which is absorbed, causes the atoms (or molecules) to move at a higher rate of speed, so that they are not staying close together, like in the liquid state. So the absorbed energy increases the kinetic energy of the atoms (or molecules).
When liquid water is heated are collisions between molecules more violent?
Yes, as water is heated, the molecules continue to speed up until they are moving so fast that they fly off which is what we call steam when you are boiling water.
Average speed of air molecules?
A thermometer. Temperture is the measure of the kinetic energy, Aka speed, of molecules.
Why would you not expect all of the molecules of air in your room to have the same average speed?
They do have the same average speed ... it's called the air temprature. I believe you need to define average for yourself.
When a gas changes into a liquid it is called and the speed of the molecules is .?
condensation and the speed decreases
When a gas changes into a liquid it is called condensation and the speed of the molecules is increased or decreased?
the speed of the molecules decreases.
What happens to the molecules in a gas as it changes back into a liquid?
trick question it dosent it turn into a liquid and then its done
Is there a chemical difference between the gauseos and liquid state of the same substance?
There is no chemical difference, the only difference is the speed in which the molecules of the substances move. Slower molecules can be solid or liquid and very high speed molecules can be gas.
What conversion do water molecules lose speed?
When water goes from a gas to a liquid, or a liquid to a solid, the water molecules have lower kinetic energy, and therefore they lose speed.
What happens to the speed of molecules in water vapor when it condenses to form a liquid?
The molecules slow down.
What happens to the speed of molecules in water vapor when it condenses to form of a liquid?
The molecules slow down.
What is volatilty in chemistry?
It is the speed in which a substance changes from a solid to liquid and a liquid to vapor
How does the mean speed of the water molecules changes as they are heated?
X
When a substance changes from a solid to a gas what happens to the speed of the molecules?
The speed doesn't change, it's just that the molecules are free to move around, rather than being restricted to a shape.
When the molecules in a body move with increased speed is it a possible that the body will change from gas to a liquid?
Liquid to a gas
How does a liquid change into a gas when it is heated?
The molecules absorb more energy, more speed and can be released from the liquid.
