What happens to the kinetic energy of a substance while undergoing a phase change?
It depends on what phase change they are undergoing. If it were going from a solid to a liquid, then the kinetic energy would be greater. Same as if it were going from a liquid to a gas. However, if it were going from a liquid to a solid (or a gas to a liquid), then the kinetic energy would decrease.
True or false freezing is from a solid to a liquid?
Matter will only change from a liquid to a solid when you take away heat.If a liquid turns into a solid when you ADD heat, then something else is happening. It could be a chemical reaction or a more simple example would be if you heat a mixture of something that has water in it and the water evaporates. What is left behind is whatever did not evaporate and could be a solid. This is technically not the same matter that you had before, so you can't say the matter turned into a solid from a liquid by adding heat.
What substance would gas change into if it was cooled?
a liquid then if cooled further it would turn into a solid a liquid then if cooled further it would turn into a solid
What is the change from liquid to solid called?
Either solidification or freezing can be used to describe the change from a liquid to a solid.You might tend to say the lava solidified into rock and the water froze into ice but actually, either term would be correct.
Is the melting of ice a physical change or a chemical change?
The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.
If you were changing a gas to a liquid to a solid what thermal change would be involved?
The thermal change that would be involved is a negative one. A gas must decrease in temperature to become a liquid and eventually a solid.
When an ice cube changes into a liquid would it require an increase or decrease?
increase or decrease in what?
Would solid to liquid increase or decrease?
The mass remains the same.

How do you call a change from liquid to solid?
The change in state would be known as freezing. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition
What process causes changes of state?
In a word, temperature. A physical change will change the matter's state based on it's temperature. For example, water, H2O. You can increase the temperature to 212oF and it will change state from a liquid to a gas. You can decrease the temperature to 32oF and it will change state from a liquid to a solid. To answer your question, the process of doing so would be increasing or decreasing temperature of matter.

How would a decrease in natality change the population?
A decrease in the birth rate will cause a decrease in population over time.
Would it be true to say that solidfication is from a liquid to gas?
False. Solidification when a substance that is in a liquid changes phase to a solid.
What is a change of state from liquid to gas which is not evaporation and has 4 letters?
If a liquid was to boil to change state, it would be changing from a liquid to a gas, and would be said to be boiling.
How would you change liquid into ice?
Freeze the liquid (put into freezer).
What change to a wire would cause its resistance to decrease?
Decreasing the length or increasing the thickness of the wire would cause its resistance to decrease.
