IB Physics SL B 3 2 Amount of Substance Questions

Practise IB Physics SL B.3.2 by using moles, molar mass and Avogadro’s constant to count particles and compare samples.

Exam points

Explain work done by a force as an energy transfer to or from a system.
Calculate work and the corresponding energy transfer from complete force–displacement evidence, using consistent units and sign conventions.

[Maximum number: 1]

This question is in two parts. Part 1 is about ideal gases and specific heat capacity. Part 2 is about simple harmonic motion and waves.
Part 1 Ideal gases and specific heat capacity

Argon behaves as an ideal gas for a large range of temperatures and pressures. One mole of argon is confined in a cylinder by a freely moving piston.

Define what is meant by the term one mole of argon.

One mole of argon is the molecular weight of argon in grams, or $6.02\times10^{23}$ argon atoms, or the same number of particles as in 12 g of carbon-12.

Allow atoms or molecules for particles.

1\ \mathrm{mol}=6.02\times10^{23}\ \text{particles}
