Terms in this set (28)

What happens to the pressure of a gas when the temp is increased? (assume a fixed volume)
pressure increase
What occurs to the pressure of a gas if the temp is lowered?
Pressure decreased
what states of matter (solid, liquid, gas) are capable of flowing
liquid & gas
What is absolute zero (definition & actual value in Kelvin)
The lowest temp, possible, 0 Kelvin
When volume is decreased, what occurs to the pressure
pressure increase
When rusting occurs, oxygen is removed from the air. As a result of this what occurs to the partial pressure of oxygen in air?
It will decrease
What happens to the total pressure of the air as a result of this reaction. (refer to #6)
it will decrease
What effect does an increase in temp have on the overall kinetic energy of the particles in a substance
Will increase the KE
When temp is constant, what effect does doubling the volume have on the pressure of the gas?
It (pressure) is cut in half
State the three assumptions of Kinetic Theory of gases
1. Gases are small spherical spheres that aren't attracted to each other
2. Gas particle's motion is rapid, random & constant
3.Collision of gas particles are perfectly elastic
What effect does adding more air (gas) to a tire have on the overall pressure
Pressure increases
What are the actual values for STP
T=0 C, P= 1 atm
What is true about the kinetic energy of any two substance that are the same temp?
KE is the same
What is the relationship between Temperature & pressure
Directly Pro (T&P)
What is the relationship between Temp & Volume
Directly Pro (V&T)
