How do you microwave popcorn?
I understand that there are special sealed containers of popcorn suitable to cook in a microwave. Apparently, there are instructions on the label. The reason why special sealed containers are used is to prevent the popcorn shooting all over the inside of the microwave. One website stated that it was possible to microwave popcorn placed inside a brown paper bag!
How does density vary with the temperature?
This depends upon the circumstances. For example, if a gas is heated inside a sealed container, the density remains the same (the gas cannot expand inside a sealed container) but the pressure increases. Eventually the container will explode, if sufficiently heated, at which point the density will decrease. Another example would be, to heat ice so that it melts into water; water is denser than ice, so in this case heating increases density. There are various other possibilities. In most cases, heat causes things to expand and become less dense.

Does hot water in a plastic bottle causes it to expand?
Not necessarily. You have to have a space of air in the bottle. The expansion/contraction happens because the water is heating/cooling the air. Liquids are usually considered incompressible and hence will not change their volume when heated or cooled (unless it evaporates or melts!). Assuming that you have an air space: If you have cold water in a sealed bottle that you heat up, it will expand. If you put hot water in a bottle and seal it, it will contract as it cools. If the bottle is not sealed, there will be no volume change.
What is a capillary melting point?
The sample is placed in a sealed capillary and heated up to the melting.

Will the center of a tornado expand or contract a bag of potato chips?
Since tornadoes generate low pressure a sealed bag would expand inside of one.
