Gases

If temperature of any gas is increased its volume

• increases

• decreases

• remains same

• none of above

The pressure resulting from the collision of air molecules with objects is called

• Kinetic theory

• Atmospheric pressure

• Vapor pressure

• Sublimation

The average kinetic energy of the particles in a substance is

• increased as the temperature of the substance increases

• unaffected by changes in the temperature of the substance

• increased as the temperature of the substance decreases

• equal to the total thermal energy absorbed by the substance

If the temperature is constant, as the pressure of a gas increases, the volume

• increases

• decreases

• doesn't change

• none of the above

As the temperature of an enclosed gas increases, the pressure _________________ if the volume is constant

• increases

• decreases

• doesn't change

• None of the above

The mathematical expression of Boyle's Law is

• $\frac{P1}{V1\ }\ =\ \frac{P2}{V2}$

• $P1\ \times\ V2\ \ =\ P2\ \ \times\ V1$

• $P1\ \times\ V1\ \ =\ P2\ \times\ V2$

• $P1\ \times P2\ =\ V1\ \times\ V2$

 $\frac{V1}{T1}\ =\ \frac{V2}{T2}\$  is 

• Boyle's Law

• Charles's Law

• Gay- Lussac's Law

• Avogadro's Law

When a gas is pumped into a closed rigid container , the pressure ____________ as more particles are added.

• decreases

• increases

• doesn't change

• None of the above
