IMF's, Thermichemistry and Types of Bonds

Question 1

Higher IMF’s?

Answer 1

Lower vapor pressure

Question 1

Higher temperatures?

Answer 1

Higher vapor pressure

Question 2

When is the boiling point of a liquid achieved?

Answer 2

When the vapor pressure of the liquid is equal to the atmospheric pressure around it.

Question 3

At higher elevations…

Answer 3

Vapor pressure is lower, water boils at a lower temperature

Question 4

At lower elevations…

Answer 4

Vapor pressure is higher, water boils at a higher temperature

Question 5

When baking at a lower air pressure

Answer 5

-Rise faster due to decreased resistance
-Moisture evaporates quicker

Question 6

Water’s surface tension

Answer 6

Water molecules have strong attractions to each other- cohesive force

Question 7

What is more dense- water or ice

Answer 7

Water is denser- when water reaches solid state the hydrogen bonds become stable arranging the water molecules far apart from each other

Question 8

Liquids with high vapor pressure

Answer 8

Have higher boiling points

Question 9

Vapor Pressure

Answer 9

The pressure exerted by a vapor that exists above a liquid surface
