Ihave made a dive then stayed on the surface for a while. after this surface interval my pressure group is k. what is the maximum amount of bottom time available when doing a repetitive dive to 17 metres/56 feet?

Argon is adiabatically compressed from an initial volume of 16 liters to a final volume of 2 liters. by what factor do the following quantities change? do they increase or decrease? (a) the rms speed (b) the thermal energy of the gas (c) the molar specific heat cv (d) the pressure

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

Observations show that interstellar clouds can have almost any shape and
