Leigh is preparing popcorn for her friends. She removes a stick of butter from the refrigerator and cuts a fourth of it from the rest.

Leigh remembers her lesson in school today about the conservation of mass that occurs during state changes. She wants to test what she learned, so she measures the mass of the butter she will melt. Its mass is 35 g. Then, she places the butter in the microwave and melts it.

What should the mass of the liquid butter be once it is melted?

15 grams

35 grams

40 grams

70 grams

Kia is doing an experiment in science lab. She is given a beaker containing 100 g of liquid. The beaker has markings on the side for measuring volume. The water comes up to the 100 mL mark. Kia puts the liquid on a hot plate by mistake. By the time she realizes the mistake, half of her liquid has evaporated.

Kia still needs 100 g of liquid for her experiment. To find out how much liquid she has to replace, she needs to re-weigh her liquid. However, the balance she used before is now broken. The teacher tells Kia that she can tell how much water is left by looking. The water now comes up to the 50 mL mark.

How much mass does Kia's remaining water have?

100 grams

50 grams

20 grams

2 grams

Mrs. Andrews did a science demonstration with dry ice. First, she placed some dry ice inside of a balloon. Then she tied off the balloon and placed it on a triple beam balance. The balance showed that the combined mass of the balloon and dry ice was 22 grams. While the balloon sat on the balance, it began to expand. As the dry ice sublimed, or changed from a solid into a gas, the gas filled the balloon. When the dry ice had sublimated completely, how much mass was sitting on the balance and why?

More than 22 grams because the balloon inflated, so its mass increased.

Exactly 22 grams because mass cannot be created or destroyed by ordinary physical changes.

Less than 22 grams because a gas weighs less than a solid.

Less than 22 grams because warm things weigh less than cold ones.
