1) A nurse measures the temperature of a patient to be 40?C. What is this temperature in the Fahrenheit scale? a) 99 b) 104 c) 85 d) 109 2) A diver has her lungs full of air and is holding her breath as she rises from the deep to the surface. Assume that the temperature T of the air in the lungs and also the moles of air molecules n remain constant. As she rises to the surface, the air pressure in her lungs is reduced by a factor of 1/3. According to the ideal gas law, the volume of air in the lungs should a) Double b) Triple c) Quadruple d) Reduce in half e) Stay the same 3) A 4.55kg block of iron is suspended from a scale and immersed in water, as in the figure. The dimensions of the block are 12.0 cm×8.0cm×8.0cm. The 12.0cm dimension is vertical, and the top of the block is 5.00cm below the surface of the water. Use this
