Three moles of an ideal monatomic gas are at a temperature of 396 K. Then 2438 J of heat is added to the gas, and 897 J of work is done on it. What is the final temperature of the gas?

Is the molar mass of SiO2 60 g/mol (I took the molar mass of Silicon-28, and added Oxygen's atmoic mass-16 and doubled it since it's diatomic). Thanks for checking my work.

An ideal spring with a force constant (spring constant) of 15 N/m is initially compressed by 3.0 cm from its uncompressed position. How much work is required to compress the spring an additional 4.0 cm?

Why was the United Nations creation more successful than the League of Nations? I know that the League of Nations was created after World War 1, but I'm not sure why it didn't work, where as the UN is still working today.
