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
