What is solid?
A solid is a state of matter that has a definite shape and volume.
100
What is a freezing point? and when does it happens?
Freezing point is simply the temperature at which it changes from a liquid to solid.

What are some signs that chemical change may have occurred.
Observable signs that a chemical change has occurred include a change in color, odor, or temperature; the production of a gas (bubbles) or a solid (precipitate); and the release of light.

What is the primary difference between physical change and chemical change?
Anything that does not change is physical change, and anything that changes is chemical change.

What is a molecule?
A molecule is a group of two or more atoms held together by the chemical bonds.
300
Is this a solid,liquid or a gas?
Liquid
300
What is temperature and how can you describe it?
Temperature is something that measures average kinetic energy of the particles in an object or substance.
400
What's the difference between a solid and a liquid?
A. The difference is that a solid has a definite shape and volume because its particles are tightly packed and only vibrate in place, while a liquid has a definite volume because its particles are less tightly packed and can slide past one another.
B. The difference is basically that liquid is liquid and solid is solid.
C. Liquid is like DHMO and solid is like frozen ice and both of them are the difference.
The answer is A. The difference is that a solid has a definite shape and volume because its particles are tightly packed and only vibrate in place, while a liquid has a definite volume because its particles are less tightly packed and can slide past one another.

- What is the main characteristic that defines a chemical change?
The main characteristic of chemical change is the change of colour,odor,shape and the visuals.
400
What is a pure substance made up of only one type of atom called?
An element
400
How are the particles in a solid, liquid, and gas different from each other in terms of energy and movement?
They are different in many like how they are, how they are aligned and stuff.
400
When does condensation appear?
It appears when the temperature or state of gas to liquid is called condensation.
500
Explain the difference between mass and weight?
Mass is amount of matter in an object, but Weight is the force of gravity acting on the mass.

Describe the differences between solid liquid Gases?
The fundamental differences between solids, liquids, and gases arise from the arrangement, motion, and energy of their constituent particles.
