A gas at 200 K occupies a volume of 350 ml. What temperature is needed to increase the volume
Rudik [331]

Answer: Temperature in constant pressure is 286 K

Explanation: If pressure remains constant, then V/T = constant.

V1 = 350 ml and T1 = 200 K and V2 = 500 ml.  V1/T1 = V2/T2

and T2 = T1· V2 / V1 = 200 K · 500 ml / 300 ml = 285,7 K

Tear off a small, flat sheet of waxed paper. Use the pipette to dispense a drop of water on the waxed paper. Now, dry the pipett
Vilka [71]

Answer:

Explanation:

When comparing the drops of oil and water, one thing I noticed was the shape. The water drop was more defined, whereas the drop of oil began to spread and was much flatter. This may be due to the waxy material, and how both oil and water react to the wax.

A mixture of three noble gases has a total pressure of 1.25 atm. The individual pressures exerted by neon and argon are 0.68
FinnZ [79.3K]

First of all, as you seen the gases are noble which means that will not react with each other and in this case each gas create individual pressure.  

P_{T}= total pressure  

P_{Ne} = pressure of neon  

P_{Ar} = pressure of argon  

P_{He} = pressure of helium {which is required}

P_{T} = P_{Ne} + P_{Ar} + P_{He}    

1.25 = 0.68 + 0.35 +  P_{He}

P_{He}   = 1.25  - [0.68 + 0.35] = 0.22 atm
