Question

question 1 - 7
pauline is curious to know if salt affects the freezing rate of water. to test her question, she labeled three identical containers #1, #2 and #3, next she filled each container with equal amounts of distilled water. she did not add any salt into container #1. she did dissolve 5g of salt into container #2 and 10g of salt into container #3. pauline placed all containers into a freezer and measured the temperature at which the water froze in each container. her data is shown below:
data table 1: temperature reading for freezing point
container of water
salt added (g) freezing point °c
1 2 3
0 5 10
0 -4.5 -10.1
how should pauline label container 1?

Explanation:

Step1: Identify the salt amount in container 1

From the table, for container 1, the amount of salt added is \(0g\).

Step2: Determine the label based on salt amount

Since container 1 has \(0g\) of salt added, it should be labeled as the container with no salt added.

Answer:

Container 1 should be labeled as the container with \(0g\) of salt added (or the control container with no salt).
