A measure of the average kinetic energy of particles
2
New cards
Standard Temperature
0C (273K)
3
New cards
Pressure
The force per unit area on a surface
4
New cards
Standard Pressure
1 atm (101.3 kPa) (760 mmHg) (760 torr)
5
New cards
Absolute Zero
The theoretical temperature where the motion of particles cease, would have no kinetic energy
6
New cards
STP
Standard Temperature and Pressure
7
New cards
Gas Laws
The simplest mathematical relationships between the volume, temperature, pressure and amount of a gas
8
New cards
Boyle’s Law
The volume of a fixed mass of gas varies inversely with the pressure at constant temperature (P1\*V1 = P2\*V2)
9
New cards
Charles’s Law
The volume of a fixed mass of gas at constant pressure varies directly with the kelvin temperature (V1/T1 = V2/T2)
10
New cards
Gay-Lussac’s Law
The pressure of a fixed mass of gas at constant volume varies directly with the kelvin temperature (P1/T1 = P2/T2)
11
New cards
The Combined Gas Law
Describes the relationship among the pressure, temperature, and volume of an enclosed gas ((P1\*V1)/T1 = (P2\*V2)/T2)
12
New cards
Avogadro’s Law
Equal volumes of gases at the same temperature ad pressure contain equal numbers of molecules (22.4L)
13
New cards
Molar Volume
1 mole of a gas at STP = 22.4 L
14
New cards
large numbers of tiny particles that are far apart
Gases consist of…
15
New cards
