Consider a sample of N 2 gas under conditions in which it obeys the ideal gas law exactly. From the following statements, true and false statements needs to be identified. A sample of Ne(g) under the same conditions must obey the ideal gas law exactly. The speed at which one particular N 2 molecule is moving changes from time to time. Some N 2 molecules are moving more slowly than some of the molecules in a sample of O 2 (g) under the same condition. Some N 2 molecules are moving more slowly than some of the molecules in a sample of Ne(g) under the same condition. When two N 2 molecules collide, it is possible that both may be moving faster after the collision than they were before. Concept introduction: An ideal gas which is known as the perfect gas is a gas whose volume V, Pressure P and temperature T are related through the ideal gas laws : - PV = nRT Here, n = number of moles of the gas R = ideal gas constant T = Temperature P = Pressure Ideal gases are described as the molecules which have negligible size but have an average molar kinetic energy which is dependent on the temperature. When temperature is low most of the gases behave like ideal gases and the ideal gas law might be applied to them.

Question

Chapter 5, Problem 5.85PAE

Interpretation Introduction

Interpretation:

Consider a sample of N₂ gas under conditions in which it obeys the ideal gas law exactly. From the following statements, true and false statements needs to be identified.

A sample of Ne(g) under the same conditions must obey the ideal gas law exactly.

The speed at which one particular N₂ molecule is moving changes from time to time.

Some N₂ molecules are moving more slowly than some of the molecules in a sample of O₂(g) under the same condition.

Some N₂ molecules are moving more slowly than some of the molecules in a sample of Ne(g) under the same condition.

When two N₂ molecules collide, it is possible that both may be moving faster after the collision than they were before.

Concept introduction:

An ideal gas which is known as the perfect gas is a gas whose volume V, Pressure P and temperature T are related through the ideal gas laws: -

$PV = nRT$

Here,
n = number of moles of the gas
R = ideal gas constant

T = Temperature

P = Pressure

Ideal gases are described as the molecules which have negligible size but have an average molar kinetic energy which is dependent on the temperature. When temperature is low most of the gases behave like ideal gases and the ideal gas law might be applied to them.
