Suppose that a 100 cm3 box in the shape of a cube is, Ask an Expert

Academics

Suppose that a 1.00 cm3 box in the shape of a cube is perfectly evacuated, except for a single particle of mass 1.21 10-3 g. The particle is initially moving perpendicular to one of the walls of the box at a speed of 205 m/s. Assume that the collisions of the particle with the walls are elastic.

(a) Find the mass density inside the box.

(b) Find the average pressure on the walls perpendicular to the particle's path.

(d) Find the temperature inside the box. in kelvins Discuss the assumption of elastic collisions, in light of this result.
