- Tire gauges for air pressure as well as most other gauges used in an industrial environment take into account the pressure due to atmosphere on earth that's why your car gauge reads zero before you put it in on your tire to check your pressure this is called gauge pressure. The real pressure with any tire or after or other objects containing pressurized stuff would be a combination of what the gauge reads as well as the atmospheric pressure. If a gauge on a tire reads 26.23 psi what is the real pressure in the tire pascals? The atmospheric pressure is 1.01×10 to the fifth power PAThe absolute pressure of a gas in an enclosed cylinder on a day is 3.67 A low pressure storm comes upthe conditions in the gas cylinder remain unchanged does the absolute pressure of the gas increase, decrease, or remain the same? What about the gauge pressure ?Please and thank you! Make sure the answer is in the correct units!
- An aquatic organism needs to be neutrally buoyant to stay at a constant depth. Fish accomplish this with an internal swim bladder they can fill with air that they take in from the water through their gills. One complication is that the pressure in the swim bladder matches that of the surrounding water, but the water pressure changes with depth. Because the volume of a gas is inversely proportional to pressure (as you may already know if you have studied the ideal-gas law), the volume of air in a fish's swim bladder decreases with depth unless the fish actively adds more air. ▼ Part A Consider a 3.9 kg freshwater fish whose tissues have an average density of 1050 kg/m³. To what volume in mL must the swim bladder be inflated for the fish to be neutrally buoyant at the surface? Express your answer in milliliters to two significant figures.
