A container with 1 mole of gas is expanded from 5 litres to 10 litres by adding more gas. the temperature and pressure are kept constant. how many moles of gas are present after the expansion.
options:102351
An ideal gas is in a cylinder with a volume of 250.0 mL at a temperature of 25 ºC and a pressure of 700 torr. The gas is expanded to a volume of 1.0 L and the temperature increased to 500 ºC.
