help!

Answer 1

Eddie experimented to find out which freezes at a lower temperature, distilled water or salt water. The steps he used in his experiment are shown below.

Fill one beaker with 250 mL of room-temperature distilled water

Fill another beaker with 250 mL of room-temperature salt water

Measure the mass of the liquid in both beakers

Place both beakers in a freezer

Observe the temperature at which the liquids freeze

Which of the steps in Eddie's experiment was NOT needed?
2
3
4
1

Answer 2

i will medal and fan!

Answer 3

Measuring the mass is not really necessary because you're set to a specific volume by using the 250 mL beakers.

Answer 4

It would be relevant if the experiment was set to determine how much salt concentration affected the freezing temperature

Answer 5

I was thinking C or B

Answer 6

I think its' "Measure the mass of the liquid in both beakers"

Answer 7

Your right!

Answer 8

Thank you!

Answer 9

sweeet, no problem !
