A friend notices that a nail that was left outside for a few months seems larger and heavier than it was before. They say it disproves the law of conservation mass. Why are they wrong?

• Some of the added mass on the nail is from oxygen gas, which was in the system but was not accounted for because it's invisible.

• Some of the added volume on the nail is from oxygen gas, which was in the system but was not accounted for because it's visible.

• The nail was physically changed when it was left outside.

• The friend switched the nail to trick the other person into thinking they disproved the law of conservation mass.

A northern right whale migrates from warm waters off Florida to cooler waters off Nova Scotia, Canada. In which area do you think more thermal energy would move from the whale to its environment?

• Canada; thermal energy probably flows from the whale to its environment at all times, but more so when its environment gets colder.

• Florida; thermal energy probably flows from the whale to its environment at all times, but more so when its environment gets colder.

• Canada; thermal energy probably flows from the whale to its environment at all times, but less when its environment gets colder.

• Florida; thermal energy probably flows from the whale to its environment at all times, but less when its environment gets colder.
