1. un gas está encerrado en un cilindro ajustado con un pistón ligero sin fricción y se mantiene a presión atmosférica. cuando se agregan 1250 kcal de calor al gas, se observa que el volumen aumenta lentamente de 12.0 a 18.2 m3. calcule a) el trabajo realizado por el gas y b) el cambio en energía interna del gas.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
