Read the passage and answer the following question(s).

Ice Experiment

A group of students set up an experiment with melting ice. They called their experiment: Experiment 1. They included the

following steps:

1. They weighed an empty beaker and recorded its weight.

2. They placed three ice cubes in the beaker on the scale and recorded its weight.

3. They found the weight of the ice by subtracting the weight of the beaker from the weight of the beaker and ice.

4. They waited for the ice to melt to water and once again recorded the weight.

5. They found the weight of the water by subtracting the weight of the beaker from the weight of the beaker and water.

6. The students compared the weight of the ice and the weight of the water after the ice melted.

The students then wanted to extend their experiment by adding salt. They called this experiment: Experiment 2. They

included the following steps:

1. They began with the beaker of water on the scale.

2. They placed salt on a scale until the scale read 5.00 g.

3. They then added the salt to the water in a beaker.

4. They recorded the weight shown on the scale.

5. They compared the weight before and after adding the salt.

What was the first step in Experiment 1?

• They placed three ice cubes in the beaker.

• They added salt to the water.

• They weighed an empty beaker.

• They recorded the weight of the water.

What was the weight of the beaker with ice in the diagram?

• 28.00 g

• 58.00 g

• 5.00 g

• 33.00 g
