Gas Laws #1

Question 1

kinetic molecular theory

Answer 1

a model to explain and predict the behaviour of gases

Question 2

kmf #1

Answer 2

gases are made up of small particles seperated by large spaces, most of the volume occupied by a gas is empty space

Question 3

kmf #2

Answer 3

gas particles are constantly movng in straight lines but random direction

Question 4

kmf #3

Answer 4

gas particles undergo elastic collision with eachother and the walls of the container, no loss of kinetic energy

Question 5

kmf #4

Answer 5

gas particles exert no force of attraction on other gasses

Question 6

what is pressure

Answer 6

force per unit area

Question 7

force

Answer 7

is the result of one object hititng another object

Question 8

how does a balloon stay inflated

Answer 8

pressure inside the balloon is equal to the pressure outside the balloon so the forces cancel out and the volume stays the same

Question 9

what is gas pressure

Answer 9

the force caused by the constant collisions between the gas molecules and the surface they come into contact with

Question 10

factors that affect gas pressure

Answer 10

1. # of gas particles: the greater the number of particles, the more collisions and higher pressure
2. temperature: inc in temperature causes molecule to move faster so more collisions with greater force resulting in inc pressure

Question 11

2 factors of boyles law

Answer 11

pressure and volume of gas

Question 12

boyles law

Answer 12

at a constant temp, the volume and pressure of a fixed mass of gas are INVERSELY proportional

Question 13

2 factors of charles law

Answer 13

volume and temperature

Question 14

charles law

Answer 14

at a constant pressure, the volume of a fixed mass is DIRECTLY proportional to its temp (in kelvin)
- as temp of gas inc, volume of gas inc proportionally

Question 15

2 factors of gay lussacs law

Answer 15

pressure and temperature

Question 16

gay lussacs law

Answer 16

at a constant volume, the pressure of a fixed mass of gas is directly proportional to its kelvin temperature

Question 17

combined gas law

Answer 17

the volume of a fixed amt of gas changed when both kelvin temp and pressure change at the same time

Question 18

partial pressure

Answer 18

pressure of gas in a gas mixture that it would exert if it were the only gas present in the same volume and same temp

Question 19

daltons law of partial pressure

Answer 19

the total pressure of a mixture of non reacting gases is equal to the sum of partial pressures of the individual gases

Question 20

gay lussac formula

Answer 20

p1/p2 = t1/t2

Question 21

boyles formula

Answer 21

p1v1 = p2v2

Question 22

charles formula

Answer 22

t1/t2 = v1/v2
