2a. (5 points) 2 moles of molecules of diatomic gas and 1 mole of monatomic soli

Question

2a. (5 points) 2 moles of molecules of diatomic gas and 1 mole of monatomic solid begin in thermal equilibrium. Let's say NONE of the modes are ever frozen. The mass of an atom of the solid is 3 times the mass of an atom of the gas. What is the ratio of the average molecular speeds of the solid compared to the gas (be specific)?

2b. (5 points) These same substances are removed from thermal contact and placed in separate thermally insulated containers (they do not interact with each other). 1 kJ of heat is added to the solid. How much heat must be added to the diatomic gas to give it the same final temperature as the solid.

Explanation / Answer

2a. I think the atoms in the molecules are regid and they cannot move. Compared to gas molecules, solid atoms/ molecules speed is very negligibel and it is zero. Then the ration of the average molecular speeds of the solid compared to the gas is '0'.

2b. The given information is not enough to calculate the heat required to the gas to require the same final temperatures.

the initial temperatures and the specific heats of substances of both solid and gas (you provided mass information and final temperature informations only)

If you can provide those aspects then I can do it.

Best wishes
