For the next two items: A playroom has dimensions 3700 mm x 4300 mm x 2500 mm. How much does the air weigh in the room if the air pressure is 1.0 atm? O 402 N 472 N O 390 N 48 N

The bulk modulus of water is B= 2.2 x 10' N/m². What change in pressure AP (in atmospheres) is required to keep water from expanding when it is heated from 16.8 °C to 38.7 °C? Number i 98.7 Units atm

A simple thermometer is formed by taking a large spherical container of volume 1.13m³ and filling it with an ideal gas. Then, a U-shaped tube is attached that is very narrow so that very little fluid/gas can fit inside the tube. The tube has a small quantity of a fluid of density 1200kg/m³ placed in it. In equilibrium at room temperature - 21.9°C - the height of the fluid on both sides of the U-shaped tube are level. This is illustrated in the image below. What is the temperature of the gas in the spherical container when the left side of the fluid is 13.25cm higher than the right side of the fluid in the U-shaped tube? Atmospheric pressure is 101000Pa. °C

What is the pressure inside the drop of mercury of radius 3.00 mm at room temperature? Surface tension of mercury at that temperature (20°C) is 4.65 x 10 N m. The atmospheric pressure is 1.01 x 10° Pa. Also give the excess pressure inside the drop.

Assume that a raindrop has a volume of 0.05 cm^3 and you need an Avogadro's number of raindrops to fill up the cubic water tank. What is the length of the edge of the tank?

Problem 1:  A certain rigid aluminum container contains a liquid at a gauge pressure of P0 = 2.02 × 105 Pa at sea level where the atmospheric pressure is Pa = 1.01 × 105 Pa. The volume of the container is V0 = 2.15 × 10-4 m3. The maximum difference between the pressure inside and outside that this particular container can withstand before bursting or imploding is ΔPmax = 2.41 × 105 Pa.For this problem, assume that the density of air maintains a constant value of ρa = 1.20 kg / m3 and that the density of seawater maintains a constant value of ρs = 1025 kg / m3. What is the maximum depth dmax in meters below the surface of the ocean that the container can be taken before imploding?
