A certain gas at temperature equivalent to 24 degrees Celsius at 10 cu.m and 160 kPa is compressed to 2.5 cu.m, what is the resulting pressure assuming isothermal conditions in kPa abs? (UP TO THREE DECIMAL PLACES ONLY)

Need help with this engineering problem.

if air is at pressure of 2200 lb/ft^3, and at a temperature of 800°R, what is the specific volume?

Problem 8.01**. An underwater microphone has a volume of 0.0140 cubic meters. Its mass is 8.50 kg. It is tethered to the ocean floor by a thin cable. The specific gravity of the ocean water at that location is 1.03. Calculate the magnitude of the tension in the cable. [1330 N (-3)]

A child takes a helium balloon on a plane from Denver (with an air pressure of 0.83 atm) on a cool day when the temperature is 20.0oC to Boston (at sea level, with an air pressure of 1.0 atm) where the temperature is 5.0oC.  Assume that no gas escapes from the balloon during the flight.  What is the volume of the balloon in Boston, relative to its size in Denver? Group of answer choices The volume in Boston is 0.79 times the volume in Denver. The volume in Boston is 0.20 times the volume in Denver. The volume in Boston is 0.87 times the volume in Denver The volume in Boston is 1.3 times the volume in Denver. The volume in Boston is the same as the volume in Denver.

5. A laboratory room keeps a vacuum with absolute pressure of 0.2 kPa. What net force does that put on a door of size 2m by 1m? [Whenever necessary, assume air as an ideal gas and consider R = 287 J/(kg.K).]
