Answer to Question #104967 in Physics for Nyx

Question

Find the total translational kinetic energy of
1.5 L of oxygen gas held at a temperature of
3◦C and a pressure of 2 atm.
Answer in units of J.

Answer 1

$$E=\frac{3}{2}nRT=\frac{3}{2}pV$$

$$E=\frac{3(2\cdot 101325)(1.5\cdot 10^{-3})}{2}=456\ J$$
