Question 1.
What does the coefficient of volumetric expansion represent?
Show hintHide hint
Think of how materials change when they are heated.
Question 2.
State the formula for calculating change in volume due to temperature.
Show hintHide hint
Recall the variables used in thermal expansion.
3Question 3.
What is the coefficient of volumetric expansion?
- A measure of mass increase
- A measure of volume increase per temperature increase
- A measure of pressure increase
Show hintHide hint
Focus on how materials react to temperature changes.
4Question 4.
True or False: For most materials, the coefficient of volumetric expansion (β) is three times the coefficient of linear expansion (α).
- True
- False
Show hintHide hint
Consider the relationship between linear and volumetric changes.
Question 5.
A steel container has a coefficient of volumetric expansion of 3 × 10^-5 °C^-1. If the initial volume is 2 m³ and the temperature increases from 10°C to 80°C, what is the new volume?
Show hintHide hint
Keep in mind to apply the formula correctly.
Question 6.
In an engineering project, a liquid with a coefficient of volumetric expansion of 4 × 10^-4 °C^-1, starting at 1.5 m³, will undergo a temperature change of 60°C. Calculate how much volume it will gain.
