Hi kinda need help 1) Describe the atomic theory of atoms. How does this help us understand differences the three states of matter?

2) What is the difference between physical change and chemical change?

3) Explain the law of conservation of mass. Give an example of how mass is conserved using numbers to justify your answer.

4) Describe how temperature influences chemical changes.

1) The atomic theory of atoms is the scientific theory that all matter is made up of atoms and when grouped together, these atoms can create the food we eat, the air we breathe, and much more!

The atomic theory relates to the states of matter because the state of matter is dependent upon the strength of the bonds between each atom. Solid matter has strong bonds, liquid has weak bonds, there are no bond within gas, and plasma has ionization.

2) Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.

3) Don't know, sorry!!!

4) Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.

Explanation: hope this helped!

yay

i love free points
