Below are sample questions representative of the exercises included on this worksheet and related 12.104 Ideal Gas Law and Kinetic Molecular Theory skill assessments:

Problem 1Difficulty: Mastery

The accompanying simulation screen shows sliders for particle amount n, volume V, and kelvin temperature T. Which slider change would keep ideal-gas pressure unchanged?

ADouble n, keep V fixed, and keep T fixed.

BKeep n fixed, double V, and double T.

CTriple n, double V, and keep T fixed.

DHalve n, double V, and make T four times as large.

Solution & Explanation:For an ideal gas, P is proportional to nT/V. The proposed change gives (0.5 × 4)/2 = 1, so pressure is unchanged.

Problem 2Difficulty: Mastery

An ideal gas sample is placed in a sealed container in orbit, where effective weight is nearly zero. Why can the gas still exert pressure on the walls?

APressure disappears whenever gravity is absent.

BPressure comes only from particles settling on the bottom wall.

CPressure comes from particle-wall collisions, not from the gas needing weight.

DPressure requires chemical bonding between particles and walls.

Solution & Explanation:Kinetic molecular theory explains gas pressure as momentum transfer during collisions with container walls. Gravity is not required for those collisions to occur.

Problem 3Difficulty: Mastery

The accompanying P-V state plot shows four states of the same amount of ideal gas: A at 1 L, 400 kPa; B at 2 L, 250 kPa; C at 4 L, 150 kPa; and D at 3 L, 300 kPa. Which state has the highest temperature?

AState A.

BState D.

CState B.

DState C.

Solution & Explanation:For the same amount of ideal gas, temperature is proportional to PV. The products are A = 400, B = 500, C = 600, and D = 900 kPa·L, so D is highest.
