What phase change is taking place when a substance goes from a gas to a liquid?
The phase change when a substance goes from a gas to a liquid is called condensation. This occurs when the temperature of the gas decreases, causing the gas particles to lose energy and come together to form a liquid.
What is the science involved in a lava lamp?
Heating and melting a substance. Also when the substance that you see starts to warm, it melts, and becomes less dense than the liquid inside that you can't see, so the substance that you can see (usually it's red) goes up.
When a substance freezes it goes from?
a state of matter where particles are in constant motion to a state where particles slow down and arrange in a more ordered pattern, resulting in a solid form.
What is meant by the solubility of a solute?
Solubility is the ability of a substance to dissolve completely in another substance. The substance that dissolves is called the solute. If the solute has a high solubility, then it easily dissolves in most substances to create a solution. If the solute has a low solubility, then it does not dissolve easily and rarely goes into solution with other substances.
What is the color of phenolphthalein indicator in acidic medium?

zigzag machine
What a substance does when it goes from a gas to a liquid?
condensation
When a substance goes from a gas to a liquid it goes through a?
Phase change.
What is the effect of the quantity of a substance on density?
If mass is constant, density goes down as volume, or quantity, goes up. In other words, if there is more of something (or it is bigger in size), and it has the same amount of matter, then it is less dense. This is because the atoms/molecules are spread out more.
The type of machine that uses a needle that goes from side to side is?
The machine that has a needle that goes from side to side is an overlock serger. It is used to prevent fabric from fraying.
What was the different of old machine gun and new machine gun?
