i just have 2 questions i want to clear up so i can understand the concepts more, thanks(adsbygoogle = window.adsbygoogle || []).push({});

1) if you are calculation entropy change from path a to b and the path is isobaric (cont. pressure) how do you do it? the formula for entropy change is dQ/T, but i am unsure about what T to use, also i cannot use mclnT2/T1 because i do not know the mass of the gas, how should i solve a problem like this?

2) if you are given the mass of an object and spring const., initial amplitude and info that the amplitude is 3/4 of what it was initially in 4 cycles, how do you calculate b, we dont know the period but do we use w^2=k/m? the question, being about damped ossilators throws me off a bit and im unsure how to start a problem like this
