Question 1.
What does temperature measure in gases?
Show hintHide hint
Think about what makes gases move faster or slower.
Question 2.
Define internal energy in the context of an ideal gas.
Show hintHide hint
Consider the relation between energy, temperature, and molecules.
3Question 3.
What does the average kinetic energy of gas molecules depend on?
- Pressure
- Volume
- Temperature
Show hintHide hint
Consider how temperature influences molecular motion.
4Question 4.
Is the root mean square speed of a gas independent of the type of gas?
- True
- False
Show hintHide hint
Think about how mass affects speed.
Question 5.
Calculate the temperature of a gas sample given that its average kinetic energy is 4.5 J for 6 moles. Use $k_B = 1.38 \times 10^{-23}$ J/K.
Show hintHide hint
Remember to find N using the number of moles and Avogadro's number.
Question 6.
Two gases are mixed: one at 100 °C with mass 2 g and another at 50 °C with mass 3 g. Calculate the total kinetic energy of the system.
Show hintHide hint
Remember to convert temperatures to absolute scale (Kelvin) first.
