What happens to matter when it undergoes a physical and chemical change?
A chemical change cant be undone and a new substance, so in other words you cant reverse the effects and in the end you get ashes. An example of a chemical change would be burning paper and getting ashes. A physical change can be undone. An example of a physical change would be bending the paper because you can still get the paper back and no new substance is created.
What are the different methods to obtain a pure substance?
Try to break it down by physical and chemical means until you cant really break it down anymore, that's your best chance of identifying it as a pure substance. To help you identify it, there are each elements physical properties,(color,shape,texture,states at different temperatures, and other things that can be observed without change to the substance.) which are better to use for observance than Chemical Properties, because they usually cant be reversed and cause change to the material.
What happens to temperature after a phase change?
During a phase change, the temperature remains constant even though heat is being added to the system. This is because the energy is being used to break intermolecular forces rather than increase the temperature of the substance. Once the phase change is complete, the temperature will start to rise again.
Do molecules have anything to do with volume?
Yes, molecules play a role in determining the volume of a substance. The number and size of molecules in a substance affect its density, which in turn influences its volume. Additionally, the packing arrangement of molecules in a substance can determine its overall volume.
Why is a cooking an egg a chemical change?
Cooking an egg is a chemical change because the heat causes the proteins in the egg white and yolk to denature, changing their chemical structure. This irreversible change alters the appearance, texture, and taste of the egg, making it different from its original raw form.
The amount of substance in you gravity cant change this?
The amount of substance in an object, or its mass, remains constant regardless of the gravitational field it is in. Mass is a measure of the amount of matter in an object, whereas weight depends on the gravitational field strength. In different gravitational fields, an object's weight may change without affecting its mass.

Why can your weight change so much but your mass cant?
If you were on another planet your weight would change because there is either more or less gravity. Think about it this way, if you were on a scale on lets say Jupiter, there would be more gravity so the gravity would be pulling you down harder, that way you would be heavier on a scale. Does that make sense? Now lets say you were on the moon. The moon has less gravity so there is less gravity pulling you down. Therefore you would weigh less. Mass is your 3D shape. Its not like you would loose your head on your way to the moon or like you would get an extra arm because your traveling to Saturn. Your shape (mass) stays the same. Your weight only depends on the amount of gravity on a planet.
