5 cards from this section. Quick, good the night before a test.
What is heat?
Think about how energy moves from hot to cold.
What does a thermometer measure?
Recall the common device used to check for fever.
What is the measurement of heat transfer?
Consider how energy is quantified in physics.
The coefficient of linear expansion determines how much a material expands with temperature. True or False?
Recall the definition of this coefficient.
A metal bar measuring 1.5 m is heated from 25°C to 75°C. Given its coefficient of linear expansion is 0.00001/°C, how much will the bar expand?
Use the linear expansion formula.
A gas occupies 2.0 m³ at a pressure of 200 kPa and a temperature of 300 K. If it expands to 4.0 m³, what is the new pressure, assuming temperature remains constant?
Refer to the concept of ideal gas law and its applications.
