[True or False] 7 False [Statement] 
Increasing temperature causes all substances to expand (increase volume). False. Many substances follow this rule but not all. Some substances do contract when their temperature increases within a range of temperatures. One of the most important (and common) example of this behavior happens when water is near its freezing temperature of zero degrees Celsius. As the temperature of heated water rises from zero to 4 degrees Celsius, it contracts. As water cools from 4 degrees Celsius to zero degrees Celsius and becomes ice, it expands. The ice is therefore less dense than water floats. This volume change explains why ice first forms on the surface and not the bottom of bodies of water.
