1.14 Una muestra de metano de 4.50 g de masa ocupa 12.7 dm3 a 310 K. Calcule el trabajo realizado cuando el gas se expande (a) isobáricamente contra una presión externa constante de 30.0 kPa hasta que su volumen haya aumentado en 3.3 dm3, y (b) isotérmicamente en 3.3 dm3.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
