### What cause the pressure to increase?

Is caused by the increase in the number of collisions of molecules of air with the inside walls of the object

### Newton (N)

The SI unit for force, it is the force that will increase the speed of a one-kilogram mass by one meter per second each second that the force is applied.

### Pascal

Defined as the pressure exerted by a force of one newton acting on an area of one square meter.

### Dalton's law of partial pressures

states that the total pressure of a gas mixture is the sum of the partial pressures of the component gases.

### Boyle's Law

States that the volume of a fixed mass of gas varies inversely with the pressure at constant temperature. PV=PV

### Charles's law

States that the volume of a fixed mass of gas at constant pressure varies directly with the Kelvin temperature. V/T=V/T

### Gay-Lussac's law

The pressure of a fixed mass of gas at constant volume varies directly with the Kelvin temperature P/T=P/T

### Combined gas law

expresses the relationship between pressure, volume, and temperature of a fixed amount of gas. PV/T=PV/T

### Gay-Lussac's law of combining volumes of gases

at constant temperature and pressure, the volumes of gaseous reactants and products can be expressed as ratios of small whole number.

### Avogadro's law

equal volumes of gases at the same temperature and pressure contain equal numbers of molecules

### Standard molar volume of a gas

The volume occupied by one mole of a gas at STP, it has been found to be 22.41410L

### Ideal gas law

The mathematical relationship among pressure, volume, temperature, and the number of moles of a gas. PV=nRT

### Ideal gas constant

the constant R, its value depends on the units chosen for pressure, volume, and temperature.

### Effusion

the process whereby the molecules of a gas confined in a container randomly pass through a tiny opening in the container.
