Pressure and Dalton's Law

The constant collisions of gas molecules with one another and the container creates

• Pressure

• A total loss in elastic kinetic energy

• A gain in elastic kinetic energy

• New molecules

Why does the bottle collapse?

• The inside and outside pressures of the bottle are equal

• Pressure atmosphere < pressure in the bottle

• Vapor pressure is crushing the bottle

• Pressure atmosphere > pressure in the bottle

Standard pressure is equal to...?

• 760mmHg

• 101.3 KPa

• 100 C

Partial pressures of a gas can be found by...?

• P_{tota l}= P₁ + P₂ + P₃ +…

• Q = MCΔT

• D = m/V

• Final - Initial

The total pressure of a mix of gases is...?

• Greater than the sum of the pressures of the mix of gases

• The sum of the partial pressures of the individual gases

• The masses of all the gases combined

• Equal to the most pressurized gas

Gases A, B, and C all exert 200mmHg in 2L containers. What is the Pressure Total when combined in the same container?

• 100mmHg

• 200mmHg

• 600mmHg

• 1000mmHg

P1 is 450mmHg and the Ptotal is 750mmHg. What is the pressure of the second gas, P2?

• 200mmHg

• 300mmHg

• 450mmHg

• 750mmHg

Four gases exert a total pressure of 6mmHg. Gas A and B exert 2mmHg each. Gas C exerts 0.2mmHg. Gas D exerts how much pressure?

• 1.5mmHg

• 2.0mmHg

• 1.8mmHg

• 2.8mmHg

True or false, the units of pressure don't matter, as long as you calculate the right number.

• True

• False

Convert 100.0 mmHg to atmospheres (atm).

1 atm = 760mmHg

• 760000mmHg

• 760mmHg

• .132mmHg

• .145mmHg
