Answer #1

P = Moles * gas constant * temperature / volume ( in L )

Pressure is directly proportional to moles

Means more amount of mole will contribute high pressure.

If moles are same then pressure will be same

If moles are different but mass of gases are same

Moles = mass / molar mass

Higher the molar mass will have low pressure

Krypton has high molar mass as compare to helium. So helium has high pressure as compare to Krypton

One mole of ethylene at 1 bar and 25C is placed inside a frictionless piston-cylinder device. The gas is then subjected to a two-step process: (1) by keeping the piston fixed with a lacking mechanism, 25KJ of heat is added via an electrical heater; and (2)the locking mechanism is then released and 15KJ of heat is removed. The second step of the process takes placed at constant pressure. Assuming ethylene is an ideal gas, determine the following: (a) The temperature...

You have two cylindrical solenoids, one inside the other, with the two cylinders concentric. The outer solenoid has length l(outer)=400 mm, radius R(outer)=50mm, and N(outer)=1000 windings. The inner solenoid has length l(inner)=40mm, radius R(inner)=20mm, and N(inner)=150 windings. The inner solenoid is centered within the outer solenoid. When the outer solenoid carries a current given by I(t)=I(0)sin(wt), with I(0)=600mA and w=100s^(-1), what is the peak emf in the inner solenoid?

The Columbus Dispatch conducted a study. Two identical football, one filled with helium and one filled with ordinary air, were used. A casual observer was unable to detect a difference in the two footballs. A novice kicker was used to punt the footballs. A trial consisted of kicking both footballs in a random order. The kicker did not know which football he was kicking. The distance of each punt was recorded, then another trial was conducted. A total of 39...
