>> An ideal gas is compressed to one-fourth of its original volume while its temperature is held constant. (Hint: solve part (b) first.) (a) If 950 J of energy is removed from the gas during the compression, how much work is done on the gas? (b) What is the change in the internal energy of the gas during the compression? << I'm really not even sure where to begin here at all. I know the formula for work is W=Qh-Qc... but Im not sure how to find the change in internal energy?
