What will happen to the water in a reservoir if people use more water, so that the flow out becomes greater than the flow in?

• The amount of water in the reservoir will increase, and may overflow.

• The amount of water in the reservoir will decrease, and may eventually run out.

In science class, Marvin studies the effects of mixing substances together. Marvin and his partner measure and collect 450 mL of warm water and 50 mL of salt in a large, glass beaker. They measure the mass of each substance and record the results in the table below.Part A: Marvin and his partner measured the mass of a large, glass beaker. They mix the two substances together in the beaker. They observed a slight color change in the water and that much of the salt disappeared after mixing the two substances. Then, they measured the mixture and subtracted the mass of the beaker so they could record the mass of the substances after they mixed them together.Which estimate is the mass of the mixture?

• 450 grams

• 909.2 grams

• 454.6 grams

• 445.4 grams

In science class, Marvin studies the effects of mixing substances together. Marvin and his partner measure and collect 450 mL of warm water and 50 mL of salt in a large, glass beaker. They measure the mass of each substance and record the results in the table below. Which statement best explains Part A?

• The water was warm and made some of the salt dissolve. When salt dissolves, it loses its mass.

• Marvin and his partner mixed the water and the salt. This made the mass of both substances double.

• The water was warm and made some of the salt dissolve. Both substances lost a little mass because they were mixed together.

• Marvin and his partner combined the water and the salt. The total mass of each substance did not change even though they were mixed together.

Lamar is studying water quality in his science class. He learns that salt water is seeping into his neighboring town’s water supply and makes the water dangerous to drink. Lamar’s teacher challenges his class to investigate ways to identify salt water without tasting it. Part A: Lamar has one glass of pure water and one glass of salt and water. The two liquids look exactly alike. What investigation can Lamar perform, without tasting the water, to find out which glass contains the salt water?

• Lamar couldn’t do it. A chemical change has taken place.

• Lamar could evaporate the water to see which cup leaves salt behind.

• Lamar couldn’t do it. It is not possible to identify clear liquids without tasting them.

• Lamar could shine a light into the water and check for salt conductivity.
