chapter 10 section 2 notes

Question 1

what is a fluid

Answer 1

a substance that can flow; therefore take the shape of its container

Question 2

a force that tends to pull adjacent parts of a liquid’s surface together, thereby decreasing surface area to the smallest possible size

Answer 2

surface tension

Question 3

two reasons why evaporation is a crucial process in nature

Answer 3

removes fresh water from the surface of the ocean

evaporation of perspiration plays an important role in keeping you cool

Question 4

properties of liquids

Answer 4

definite volume
takes shape of container
can flow
relatively high density 
incompressible
diffuse
surface tension

Question 5

how does the kinetic molecular theory explain relatively high density of liuquid

Answer 5

relatively close together

Question 6

how does the kinetic molecular theory explain ability to diffuse

Answer 6

liquid particles are in constant motion

Question 7

how does the kinetic molecular theory explain ability to evaportae

Answer 7

some particles have enough kinetic energy to escape into the gas state

Question 8

explain why a meniscus forms

Answer 8

capillary action

force of adhesion
