Chapter 13 Section 2

Question 1

True or false the particles in a gas sample are far enough apart that size has very little influence on the volume occupied by a gas

Answer 1

True

Question 2

Avogadro’s principle

Answer 2

equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.

Question 3

The volume that one mol occupies at 0.00°C and 1.00 amt pressure

Answer 3

Molar Volume

Question 4

Standard temperature and pressure (STP) 

Answer 4

The conditions of 0.00°C and 1.00 amt

Question 5

What can you use as a conversion factor whenever a gas is at STP

Answer 5

You can use 22.4 L / mol as a conversion factor

Question 6

Ideal gases

Answer 6

Gases who’s particles occupy a negligible volume and are far enough apart that they exert minimal attractive or repulsive forces to one another

Question 7

What is the symbol of the ideal gas constant?

Answer 7

R

Question 8

The ideal gas law

Answer 8

When gas held at constant temperature the products of pressure and volume is a constant

Question 9

PV = nRT

P= pressure
V= volume
n= the number of moles
R= ideal gas constant

Answer 9

The ideal gas law formula

Question 10

True or false
even though no gas is truly ideal, most gases will behave like ideal gases at a wide range of temperatures and pressures.

Answer 10

True

Question 11

When is the ideal gas law not likely to work for a real gas

Answer 11

At high Pressures and low temperatures

Question 12

Why don’t polar gases behave as ideal gases

Answer 12

Because polar gas molecules such as water vapor is generally have larger attractive forces between their particles.
