A 500-gram block of solid cheese is melted in a pot. Which is most likely the mass of the cheese after it is melted?

• 500 grams, because the cheese does not gain or lose mass just because it was melted

• 499 grams, because some of the cheese evaporates as it melts

• 502 grams, because the cheese absorbs heat as it melts

A student notices that an inflated balloon gets larger when it is warmed by a lamp. Which best describes the mass of the balloon as a result of this change?

• The mass of the balloon increases because the size of the balloon has increased.

• The mass of the balloon increases because the temperature of the balloon has increased.

• The mass of the balloon stays the same because the gas inside the balloon still has the same mass after it warms up.
