Is a Physical change Reverible?
Yes
Is a solid able to compress?
No
What is the definition of a Liquid?
A liquid has some kinetic energy and has a definite volume but not shape.
Is baking a cake. Physical or chemical change,why
Chemical change,because the ingredients in the batter are in a new substance and aren't reversable
Which one is an example of a gas? #1 oxygen,#2 soup,or water
The correct answer would be #1,oxygen
What is the definition of a solid?
A solid is densely packed and has a definite shape and a definite volume, and has a lot of kinetic energy.
True or false,and why, chopping wood is a chemical change because it is shorter wood
Definitely false. Because even if it is shorter wood it is still would and a new substance wasn't created.
True or false, A solid has a lot of kinetic energy!
False, a solid has little, to no kinetic energy.
True or false, even if a substance mixed with another one to make a new substance it could still be a physical change
true
True or false a liquid has some more kinetic energy than a solid does.
True
Like the other one, why is ice to water a physical change even though ice is a different a different substance?
Even if it makes a new substance ice can melt to turn into water and water can freeze to ice so it is reversible. Which makes it a physical change
What is the Melting point of a solid and evaporating point of a liquid?
The Melting point is 0 decrees Celsius and the evaporating point is 100 decrees Celsius.
