states of matter

Question 1

What is matter made up of?

Answer 1

tiny particles in atoms and molecules

Question 2

What are the 4 states?

Answer 2

solid, liquid, gas, and plasma

Question 3

What is kinetic molecular theory?

Answer 3

the scientific explanation of the behaviour of matter based on all matter being made of particles that possess kinetic energy.

Question 4

What is KMT? (2 point)

Answer 4

kinetic energy is the energy of motion
even though we cant see with our naked eye, particles are always moving and therefore possess kinetic energy.

Question 5

What does energy do to particles?

Answer 5

energy makes particles move. the more energy particles have, the faster they can move and the further apart they can get.

Question 6

When do particles stop moving?

Answer 6

Zero Kelvin which is -273.15 Celcius

Question 7

Particles in solid: 3 points

Answer 7

-are very close together
-particles vibrate but cannot move around
-particles attract one another strongly in a rigid structure

Question 8

Particles in liquid

Answer 8

particles are very close together but can move around
-particles slip and slide past and revolve around each other but stay close together
-they attract one another less strongly than solids

Question 9

Particles in gas:

Answer 9

-particles are very far apart compared to their size
-they move randomly and quickly in straight lines
-attraction to one another is effectively zero
