Chapter 5

Question 1

define an ideal gas

Answer 1

ideal gases don’t have any interactions and obey the gas laws.

Question 2

whats pressure

Answer 2

pressure is the measure of force over a defined area
P= F/A

Question 3

Whats the SI unit of pressure

Answer 3

pascal

Question 4

State all unit equalities of pressure

Answer 4

1 atm= 101.325 KPa= 760 torr=760 mm Hg

Question 5

Whats a barometer and how does it work

Answer 5

tool that meausre atmospheriec pressure.
the mercury within a tube flows out into a dish until pressure exerted by mercury column=pressure of air on the rest of surface

Question 6

What STP and SATP, and their respective conditions

Answer 6

Standard temperature et pressure: 0 C/273 K, 101.325 KPa, 1 mol=22.4 L
Standard atmospheric temperature and pressure: 25 C/298 K, 101.325 KPa, 24.8 L= 1mol

Question 7

State Boyle’s law and its properties

Answer 7

P1V1=P2V2
where T and n are constant and P and V are inversely proportional

Question 8

State Charle’s law and its properties

Answer 8

V1/T1=V2/T2
P and n are constant and V and T are directly related

Question 9

State Avogadro’s law and its properties

Answer 9

n1/V1=n2/V2
where P and T. are constant and n and V are directly proportional

Question 10

Define absolute 0

Answer 10

0k where there is no more movement within particles

Question 11

Define ideal gas law

Answer 11

PV=nRT

Question 12

Whats the symbol of universal gas constant

Answer 12

R

Question 13

True or false
The temperature of a gas can be calculated in Celsius

Answer 13

False, always in kelvin
