Below are sample questions representative of the exercises included on this worksheet and related 9.66 Thermal Expansion and Material Behavior skill assessments:

Problem 1Difficulty: Mastery

An observatory instrument uses bearings that must stay aligned across cold nights and warm days. Which design choice best applies thermal expansion and material behavior?

AIgnore expansion because alignment matters only in liquids.

BChoose materials only by color, because color controls all expansion.

CUse matched-expansion materials with flexure points that allow small predictable movement.

DUse a random mix of high-expansion materials and rigid clamps.

Solution & Explanation:Precision instruments need predictable dimensional behavior. Matched materials and flexures reduce stress and preserve alignment through temperature changes.

Problem 2Difficulty: Mastery

A road surface shows cracks after a winter with frequent freezing water and large day-night temperature swings. Which explanation best separates the two expansion effects?

ABoth effects require pavement atoms to become larger when cooled.

BIce contraction pushes cracks wider, while pavement never changes size with temperature.

CIce expansion can push cracks wider, while thermal cycling expands and contracts the pavement itself.

DNeither effect involves force or volume change.

Solution & Explanation:Freezing water expands in cracks, and pavement also expands and contracts with temperature. Both can create stress, but by different mechanisms.

Problem 3Difficulty: Mastery

A sealed metal container holds gas and is left in a warmer environment. The container expands only slightly. Which statement best predicts the gas behavior inside?

AThe gas loses all kinetic energy because the metal blocks heat.

BThe gas contracts strongly because all heating causes contraction in sealed containers.

CGas particles become larger atoms, so pressure must decrease.

DGas particle speed and pressure increase because volume cannot increase much.

Solution & Explanation:When gas is heated in a nearly fixed volume, particles move faster and collide more forcefully with the container walls, increasing pressure.
