Chemistry: KMT Gas Laws
What is kinetic energy?
the energy of motion
What is pressure?
the amount of force over a given area
Why stepping on a nail is more painful than lying on a bed of nails?
force is spread out over a greater area, thus decreasing the pressure
What is 33.6 kPa converted to atm?
0.33 atm converted to kPa
What is 0.829 atm converted to mmHg?
630.04 mmHg converted to atm
What are the four variables used to describe gases?
Pressure, temperature, volume, and amount in moles
What happens to pressure when temperature is increased?
Pressure increases (G-L law)
What happens to pressure when volume is increased?
Pressure decreases (Boyle's Law)
What happens to pressure if moles of gas is increased?
Pressure increases (IG Law)
The air inside a bike pump is compressed from 2L to 1L and T remains constant. What happens to pressure?
As pressure increases volume ______ meaning they are _______ proportional
decreases; inversely (Boyle's Law)
As temperature decreases pressure _______ meaning they are _____ proportional
decreases; directly (G-L Law)
As volume increases temperature _____ meaning they are _____ proportional
increases; directly (Charles' Law)
As pressure increases the number of moles (n) ____ meaning they are ______ proportional
increases; directly (IG Law)
An inflated balloon in your car on a cold winter day; what happens to volume?
Balloon volume will decrease (Charles' law)
What is 35C to K?
308K to C
What is -12C to K?
261K to C
What is Gay-Lussac's Law?
The temperature of a gas is directly related to the pressure if the volume is kept constant
What is Boyle's Law?
The volume of a gas is inversely related to the pressure if temperature remains constant
What is Charle's Law?
The temperature of a gas is directly related to volume if pressure remains constant
What is why you don't put an aerosol can in the fireplace (which gas law?).
Because it will explode according to Gay-Lussac's law
What is standard Temperature (in K) and pressure? (in atm)
273K and 1 atm
How does the average kinetic energy of a collection of particles change with temperature?
Particle energy increases with an increase in KE.
