### Is KMT Imperfect? If so, why?

It is imperfect. This is because KMT is an assumption, and therefore does not work all the time.

### What are the assumptions of the KMT?

1.Gas particles don't attract or repel

2. Gas particles are smaller than the distance between them

3. Gas particles are in constant, random motion

4. No kinetic energy is lost when gas particles collide with

each other or with the walls of the container

5. All gases have the same average kinetic energy at a given

temperature

### Changing either the temperature, volume, number of gas particles or pressure, it affects all of ____.

the other three.

### What is Dalton's law of Pressure and Formula?

Total pressure of a gas mixture=sum of pressures of the gases in the mixture.

P total= P1+P2+P3......

### What is Boyle's Law and Formula?

If T is constant, there exists and inverse relationship between volume and pressure.

P1V1=P2V2

### What is Charle's Law and Formula ?

If P is constant, there relationship between V and T is directly proportional.

V1/T1=V2/T2

### What is Guy-Lussac's Law and Formula?

If V is constant, the relationship between P and T is directly proportional.

P1/T1=P2/V2

### What is the Combined Gas Law Formula?

P1**V1/T1=P2**V2/T2

(assuming the amount of gas in the system is CONSTANT)

### What do the letters in PV=nRT stand for?

P=pressure (atm) V= Volume (L) n=moles R= constant (.821)

T= temperature (KELVIN)
