Question

1. One molecule of ¹⁹F₂ and one atom of ³⁸Ar are separately flying through an otherwise perfect vacuum. Their temperatures are both 300 K. Which species moves faster, or do they move at the same speed?
2. Provide a single equation to show that Joules are equivalent to kgm^2/s^2
3. A single atom in a mole of ²⁴⁰U gas stored in a 1000 L container decays to ²⁴⁰Np. Assuming both species are ideal gases and that the temperature is 1000 K, what’s the partial pressure of ²⁴⁰Np?
