Solving problems in pairs

At the beginning of the activity, each student will get a folded piece of paper.
On one or two of these papers will be written the word “spy.”
In each corner of the room is a sign with the letter a, b, c, d, or e.
You will answer each question by standing next to the correct sign.
The spies’ job is to answer the question incorrectly and convince others to join them.
After all students have moved to the answer they think is correct, one person from each answer will have a few seconds to explain their reasoning, and convince others to join them.

Spy!

Check your work with the teacher often!

Conclusion:

State the basic assumptions of the kinetic theory of gases. [4]
State what is meant by a mole. [2]
Explain whether the collisions between the molecules of an ideal gas are elastic or inelastic. [2]

The kinetic theory of gases is based on some simplifying assumptions. The molecules of the gas are assumed to behave as hard elastic identical spheres. State the assumption about ideal gas molecules based on
the nature of their movement [1]
Their volume [2]
State what is meant by the Avogadro constant NA. [2]
Use the kinetic model to explain the pressure exerted by a gas. [4]

Reflection:

1) What are some of the conditions of MKT?
2) What is the ideal gas equation?
3) What is vrms?
4) What is the formula for the average kinetic energy of a particle of a gas?
