a. Compare solids, liquids, and gases in terms of the way their volumes change (or don't change) when placed into different containers.

b. A sample of gas in a rigid container that cannot change volume. Use the kinetic molecular theory to explain why the pressure in the container will decreases as the temperature rises.

c. Write one or two sentences to describe how heat will flow between two objects of different temperatures that are touching.

d. Write one or two sentences to compare the internal energy of a molecular gas with the internal energy of a monatomic gas.

e. Potential energy from intermolecular forces is included in the internal energies of which states of matter?

f. What is the average velocity of atoms in 1.00 mol of krypton (a monatomic gas) at 347 K? For m, use 0.0838

g. What is the internal energy of 4.00 mol of diatomic nitrogen gas N2, at 455 K?

a) Solids keep shape, liquids take shape of containers but don't spill, gases take container's shape and spill out

b) if you heat gas, speed of its molecules will increase and they'll push the container's walls stronger, so the pressure will increase when the container heated

c) Heat flows from warmer to colder bodies

d) For monatomic gases it's U=1.5nRT only, molecular gas has bonds between atoms so total internal energy increases

What is monoatomic?

A molecule composed of simply one atom, and missing any covalent bonds. The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are all monoatomic, while the maximum different gases are a minimum diatomic. Approximate Composition of the surroundings on the Earth's floor. Nitrogen.
