Under which conditions of temperature and pressure would a 1-liter sample of a real gas behave most like an ideal gas?(1) 100 K and 0.1 atm
(2) 100 K and 10 atm
(3) 500 K and 0.1 atm
(4) 500 K and 10 atm

Answers

Answer 1
Answer:

Answer : The correct option is (3) 500 K and 0.1 atm.

Explanation :

A real gas behaves ideally at high temperature and low pressure.

The ideal gas equation is,

PV=nRT

where,

P = pressure of gas

V = Volume of gas

R = Gas constant

T = temperature of gas

n = number of moles of gas

The ideal gas works properly when the inter-molecular interactions between the gas molecules and volume of gas molecule will be negligible. This is possible when pressure is low and temperature is high.

Therefore, the correct option is (3) 500 K and 0.1 atm.
Answer 2
Answer:

Answer:

The correct answer is (3).

Explanation:

A real gas can behave ideally at high temperatures and low pressures. The ideal gas is correctly characterized when the intermolecular interactions between the gas molecules and the volume of the gas molecule are negligible. This is only possible when system conditions are at low pressures and high temperatures.

Have a nice day!

A machine called a centrifuge is used in _____.

Answers

Answer:

The given blank can be filled with separation.

Explanation:

A technique, which is used for distinguishing particles from a solution on the basis of shape, size, the viscosity of the medium, density, and rotor speed is known as centrifugation. The machine used for this purpose is known as a centrifuge. The centrifuges majorly have an application in science, and for this centrifugal force is used that distinguishes liquids, which exhibits distinct weights.

A gas occupies 12.3 l at a pressure of 40 mm hg. what is the volume when the pressure is increased to 60 mm hg

Answers

From boyles law.
P1v1=P2v2
So,12.3×40=v×60
V= 12.3×40/60
8.2
Boyle's Law states an inverse relationship between volume and pressure. If the constant of proportionality is 12.3×40 which is 492, the volume would be 492÷60 which is 8.2.

Answer is 8.2 I
