Compare solids, liquids, and gases in terms of their shape when placed into different containers. (3 points) b. a sample of gas is in a rigid container that cannot change volume. use the kinetic molecular theory to explain why the pressure in the container will increase as the temperature increases. (2 points) c. write one or two sentences to describe how heat will flow between two objects of different temperatures that are touching. (1 point) d. write one or two sentences to compare the internal energy of a molecular gas with the internal energy of a monatomic gas.

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.

Four identical lab carts each have a mass of 200 kg. different masses are added to the carts and the velocities are measured. all carts move to the right.
