Front

What causes thermal expansion in materials?

Back

Particles gaining energy and vibrating more vigorously.

Front

Which type of thermal expansion refers to an increase in one dimension (length)?

Back

Linear Expansion.

Front

What is a key use of lead in the medical field?

Back

Radiation shielding.

Front

Which metal is commonly used in aircraft and automotive parts?

Back

Aluminum.

Front

What type of expansion involves an increase in surface area?

Back

Area Expansion.

Front

Define thermal expansion.

Back

The increase in volume of a material as its temperature rises.

Front

What is volumetric expansion?

Back

Expansion that occurs in three dimensions, increasing the volume of an object.

Front

Explain thermal contraction.

Back

The decrease in volume of a material as its temperature decreases.

Front

What is the formula for linear expansion?

Back

ΔL = αL₀ΔT, where ΔL is the change in length, α is the coefficient of linear expansion, L₀ is the original length, and ΔT is the change in temperature.

Front

What is the coefficient of thermal expansion?

Back

A numerical value that represents how much a material expands per degree of temperature increase.
