chapter 15

consider a sample of water at 0 degrees C. If the temp is slightly increased the volume of the water

decreases

ice has a lower density than water because ice

is made of open structured, hexagonal crystals

a temperature difference of 25 degrees celsius is also equal to a temp difference of 25 on the

kelvin scale

if the specific heat of water were lower than it is, ponds in the cold of winter would be

more likely to freeze

the fact that a thermometer "takes its own temperature" illustrates

thermal equilibrium

during a very cold winter, water pipes sometimes burst. The reason for this is

water expands when freezing

before ice can form on a lake, all the water in the lake must be cooled to

4 degrees c

the fact that desert sand is very hot in the day and very cold at night is evidence that sand has

a low specific heat

aluminum has a specific heat capacity more than twice that of copper. Place equal masses of aluminum and copper wire in a flame and the one to undergo the fastest increase in temperature will be

copper

when a bimetallic bar made of copper and iron strips is heated, the bar bends toward the iron strip. The reason for this is

copper expands more than iron

when you touch a cold piece of ice with your finger, energy flows

from your finger to the ice

the moderate temp of islands throughout the world has much to do with the waters

high specific heat
