3 cards from this section. Quick, good the night before a test.
What is thermal expansion?
Think about how materials respond when they get warm.
How do liquids behave in thermal expansion?
Consider what happens to water when heated.
What is thermal expansion?
Consider the effect of heat on materials.
True or False: Gases expand uniformly when heated.
Think about how gas behaves in a balloon when heated.
A concrete bridge has a length of 50 m at 10°C. If the temperature rises to 40°C, calculate the change in length given that the coefficient of linear expansion for concrete is 1.0 x 10⁻⁵ °C⁻¹.
Remember the formula for linear expansion.
A gas in a container has a volume of 5.0 L at 25°C. If it is heated to 75°C, calculate the new volume assuming a constant pressure, and use the coefficient of volumetric thermal expansion for the gas as 3.0 x 10⁻³ °C⁻¹.
Apply the volumetric expansion formula.
