Heat Misconceptions

Concepts

When objects are heated the space between the particles increases

Misconceptions

When objects are heated the particles expand and contract when they cool.
Thinks expand to make room for the heat.
Heat is an object or something other than energy.
Temperature depends on the material. Metal is colder than fabric. Coats are warm.
Temperature depends on size.
Heat travels like a liquid through conductors.
If you mix 40 degree water with 40 degree water you get 80 or more than 40.
Somethings are hotter than others are even though they have been in the same room, oven, water… for a long period of time.
Metal is hotter or colder than other objects.
Blankets, coats, warm objects. Because clothes keep you warm, anything closed in is warm, it acts as insulation and warms it up, it protects it from outside stuff, it’s like a house.
Hot water freezes faster than cold - hot water molecules evaporate when heated making less molecules that need to freeze. Steam produced need not to be frozen. When cold water freezes the ice crystals act as a barrier not a helper. Hot water molecules are farther apart giving room in which to freeze. There is less oxygen and carbon dioxide making it easier to freeze. When molecules are closer together they do not have as much of a chance of freezing where as in the hotter they are farther apart which gives them a better chance to freeze.
