kinetic model of matter

Question 1

kinetic model of matter

Answer 1

states that the tiny particles that make up matter are always in continuous random motion

Question 2

Brownian motion

Answer 2

refers to the observed random movement of particles in a fluid

Question 3

effects of a rise in temp on matter (s,l,g)

Answer 3

avg KE of particles increases, solid particles vibrate more vigorously about their fixed position, liquid and gas move about freely at higher speeds and collide with one another more frequently

Question 4

pressure in gas

Answer 4

when an air molecule collides with the inner wall of the container, a force is exerted on the wall. reaction force is exerted on the air molecule upon the collision

Question 5

pressure temperature rs (gas)

Answer 5

temperature increase, air particles gain KE, collide more frequently and more vigorously. pressure increase
directly proportional

Question 6

pressure volume rs (gas)

Answer 6

volume decreases, number of molecules per unit volume increases, collide more frequently and more vigorously, pressure increases
inversely proportional

Question 7

volume temperature rs (gas)

Answer 7

temperature increases, air particles gain KE, collide more frequently and more vigorously, pressure increases
gas pressure exceeds atm pressure, a net upward force acts on the free moving piston pushing it upwards, volume of gas increases, number of molecules per unit volume decreases, frequency and pressure decreases
vol and temp are directly proportional
