3. Under normal conditions, hydrogen, behaving like an ideal gas, expands isobarically to a volume of 0.2 m3. The mass of hydrogen is 0.01 kg. You need to calculate:
1) number of moles of gas;
2) initial volume of the system;
3) the work done by the system during such a transition;
4) amount of heat and change in internal energy.
