Chapter 5: Problem 2

List the physical characteristics of gases.

Short Answer

Expert verified
The physical characteristics of gases include expansion, fluidity, low density, ability to diffuse and effuse, and high compressibility.

Step by step solution

01

Expansion

Gases have the property of expansion. They imperatively do not have a specific shape or volume but expands to fill any container they are in.
02

Fluidity

Just like liquids, gases have the property of fluidity. They flow very easily and can move quickly, which is why the smell of perfume can fill a room quickly.
03

Low Density

Gases have very low density as compared to solids and liquids. This is because gas particles are very far apart from each other.
04

Diffusion

Gases diffuse into other gases. This means that they spread out to fill their container evenly and completely, without needing to be stirred or shaken.
05

Effusion

Gases have the ability to effuse which means they can pass through a small hole rapidly.
06

Compressibility

Gases are highly compressible. If pressure is applied, the gas particles are forced closer together.

Most popular questions from this chapter

The pressure of \(6.0 \mathrm{~L}\) of an ideal gas in a flexible container is decreased to one-third of its original pressure, and its absolute temperature is decreased by one-half. What is the final volume of the gas?

Which of the following statements is correct? (a) Heat is produced by the collision of gas molecules against one another. (b) When a gas is heated, the molecules collide with one another more often.

At what temperature will He atoms have the same \(u_{\mathrm{rms}}\) value as \(\mathrm{N}_{2}\) molecules at \(25^{\circ} \mathrm{C} ?\)

Nitrous oxide \(\left(\mathrm{N}_{2} \mathrm{O}\right)\) can be obtained by the thermal decomposition of ammonium nitrate \(\left(\mathrm{NH}_{4} \mathrm{NO}_{3}\right) .\) (a) Write a balanced equation for the reaction. (b) In a certain experiment, a student obtains \(0.340 \mathrm{~L}\) of the gas at \(718 \mathrm{mmHg}\) and \(24^{\circ} \mathrm{C}\). If the gas weighs \(0.580 \mathrm{~g},\) calculate the value of the gas constant.

A certain amount of gas at \(25^{\circ} \mathrm{C}\) and at a pressure of 0.800 atm is contained in a glass vessel. Suppose that the vessel can withstand a pressure of 2.00 atm. How high can you raise the temperature of the gas without bursting the vessel?
