1A The Kinetic Particle Model

Question 1

What happens when Particles collide

Answer 1

Kinetic energy can be passed between them

Question 2

The Greater the kinetic energy of the particles…

Answer 2

the further apart they will be

Question 3

The amount of energy contained can be reflected through…

Answer 3

the different states of matter

Question 4

The Kinetic particle model of matter

Answer 4

All matter consists of small particles that are in constant motion. the greater the energy contained by a material, the greater the amount of movement of these particles

Question 5

What causes an object expand ?

Answer 5

as energy is added to a substance, the particles gain more kinetic energy and move further apart

Question 6

Thermal Expansion

Answer 6

As energy is added to a substance, the particles gain more kinetic energy and move further apart. this causes the object to expand.

Question 7

Internal Energy

Answer 7

the total energy contained within a system ( or Substance), and includes both the kinetic and potential energy of its particles

Question 8

Kinetic energy

Answer 8

the energy of motion. particles with more kinetic energy vibrate, rotate, or move faster

Question 9

Potential energy

Answer 9

the energy stored sue to the interactions or arrangement of the particles

Question 10

What happens when a substance’s heat is increased ?

Answer 10

it increases its internal energy by increasing the kinetic energy ( temperature ) or the potential energy of the particles ( change of state)
