A shipwreck salvage company uses a lifting bag to raise a cannon off the sea bed. The bag is inflated with nitrogen to a volume of 5 m³ at the sea bed pressure of 300 kPa. Assuming no change in temperature, what would the volume of the lifting bag be at sea level where the pressure is 100 kPa?

In a system, when potential energy decreases, then entropy also decreases. true false

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?
