What happens to the volume of the gas as the pressure is doubled from 100 kPa to 200 kPa?
When the cylinder has a volume of 1 L, the gas exerts a pressure of 100 kPa. When the volume is halved to 0.5 L, the pressure is doubled to 200 kPa. Increasing the volume of the contained gas has the opposite effect. If the volume is doubled, the particles can expand into a volume that is twice the original volume.
How do you convert pressure to volume?
The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.
What is the pressure of the gas in kPa?
1000 Pa

What is P-Delta effect in tall buildings?
According to the building codes the P-Δ or P-Delta effect is the sudden changes in ground shear, overturning moment, and/or the axial force distribution at the base of a tall structure or structural component when it is subjected to a lateral forces or critical lateral displacement.
Why P-Delta analysis is done?
P-Delta Analysis is a type of analysis that is particularly important for laterally displacing multi-storey building structures experiencing a gravity load.
What is the atmospheric pressure at 50 km?
0.1 kPa
The air is so thin at an altitude of 31 miles (50 kilometers) that it exerts a pressure of only 1 mb (0.1 kPa). Even at a height of 5,000 feet (1,500 meters), the atmospheric pressure is low enough to produce mountain (altitude) sickness and other severe physical problems in some people.
What is atmospheric pressure at sea level in kPa?
101 kPa
Normal atmospheric pressure at sea level is about 101,000 Pa; namely 101 kPa (kiloPascals).
What is the reading when the pressure is at 1 atmosphere?
An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases.
