Answer 2

yes

Question 3

Is it true that kinetic energy is conserved in a gas particle during a collision.

Answer 3

yes

Question 4

How much attraction do gas particles have between each other?

Answer 4

very little

Question 5

Answer 5

hotter the temperature the more kinetic energy

Question 6

What are the 3 ways gases behavior can be effected?

Answer 6

Pressure
Temperature
Volume

Question 7

What is the formula to calculate pressure?

Answer 7

P = Force/Area = F/A

What is the standard pressure at sea level in (atm, pa, kpa, mmHg)

Answer 8

1 atm
101 325 Pa
101.3 kPa
760 mmHg

Question 9

How do you convert between atm to pa?

Answer 9

1atm = 101 325 Pa

Question 10

How do you convert between atm to mmHg?

Answer 10

1atm = 760mmHg

Question 11

Define temperature and state how it is measured.

Answer 11

temperature is define as heat energy of particles. It is measured by kinetic energy and particle movement (KE=1/2mv^2)

Question 12

How do you convert between Celsius and Kelvin?

Answer 12

K= Celsius + 273.15

Question 13

What are the SI units

Answer 13

Joules (J), Kilograms (kg), Velocity ( m/s)

Question 14

What is 1 meter^3 equal to in liters

Answer 14

1m^3=1000L

Question 15

define the three gas laws and their formulas

Answer 15

Gay-Lussac’s law – Temperature and pressure
𝑃_1/𝑇_1 = 𝑃_2/𝑇_2

Charles’ Law – Temperature and volume
𝑉_1/𝑇_1 = 𝑉_2/𝑇_2

Boyle’s Law – Pressure and volume
𝑃_1 𝑉_1= 𝑃_2 𝑉_2

Question 16

What is Avogadro’s hypothesis?

Answer 16

that equal volumes of gas at the same temperature and pressure contain the same number of particles

Question 17

How much volume does 1mol of gas occupy at standard temperature pressure?

Answer 17

22.4L

Question 18

What is the temperature at standard pressure?

Answer 18

0 degrees Celsius

Question 19

What is the temperature at standard laboratory conditions?

Answer 19

25 degrees Celsius

Question 20

How much volume does 1mol of gas occupy in standard laboratory conditions?

Answer 20

24.5L

Question 21

What is the Molar Volume formula?

Answer 21

“V1” /”n1” = “V2 “ /”n2”

Question 22

What is the Combined Gas Law formula?

Answer 22

“P1V1” /”T1 “ = “P2V2 “ /”T2 “

Question 23

Define Dalton’s Law of Partial Pressures and state the formula

Answer 23

The total pressure exerted by a gas mixture is the sum of the partial pressures of the gases in that mixture
PT = P1 + P2 + P3 + …..

Question 24

State the General Gas Equation

Answer 24

PV=nRT
P = pressure 
V = volume 
n = number of mols 
R = universal gas constant 
T = temperature

Question 25

What are the three values of R?
