1.) How will the ice water mix with the salty water? Write your hypothesis below.

(I can't add the picture of the chart so bear with me)

Solution - Hypothesis Describing Mixing - Hypothesis Describing Temperature

(Will the top be warmer, cooler, or the same as the bottom?)

Solution 1

(Freshwater) - -


Solution 2

(salty water) - _____________________ - ________________________


Solution 3

(saturated water)- ______________ - _____________________


2.) Complete the data table. Sketch, use your computer to draw or write a detailed description to describe how the ice melts into the different solutions. At each interval, record the temperature at the top and bottom of the glass.

(Again I can't add the pic of the chart so bear with me)


Solution 1 - 0 minutes- 5 minutes- 10 minutes- 30 minutes-

(Freshwater)


Temperature

(top of glass) -______________________________-

Temperature

(bottom of the glass)-_______________________________-


Solution 2- 0 minutes- 5 minutes- 10 minutes- 30 minutes-

(salty water)


Temperature

(top of glass)- ____________________________________-

(bottom of glass)-_______________________________________


Solution 3

(saturated water)- 0 minutes- 5 minutes- 10 minutes- 30 minutes-


Temperature

(top of glass)-___________________________________

Teperature

(bottom of glass)-_______________________________________


3.) Summarize your data. Describe how the ice melted into each solution, and compare the temperatures at the top and bottom of the glass.

(can't add the pic, bear with me)

Solution-
Mixing (how did the colord, fresh, melt-water mix with the salty water?)- Temperature (Was the top warmer or cooler, or was it the same as the bottom?) -


Solution 1

(freshwater)-__________________________________________-

Solution 2

(salty water)-___________________________________________

Solution 3

(saturated water)- ____________________________________


4.) What does your experiment suggest about what happens when icebergs melt into the ocean? Based on your data, do you think the sea-surface temperatures are warmer or cooler due to the melting water? Make sure you explain how your experiment helps you answer this question.


I really need help with this as soon as possible, if you do not know the answer to this do not answer please, let me repeat that, PLEASE DON'T ANSWER IF YOU DON'T KNOW THE ANSWER TO ALL THE QUESTIONS, also if your a k12 student, friend me so we can help each other with quizzes and stuff, and if you are a k12 student and you answer this, please don't put your exact answers on this, make it different from yours, I don't want a heart-attack email from my teacher

Answer 1

The way ice water mix with the salty water is that  when a person adds salty water to ice, the salt will be the first thing to dissolves in the layer of liquid water that is seen on the surface.

By reducing the  freezing point below the ices temperature, when the Ice is said to be in contact with salty water, it tends to melts, forming more liquid water, that will then dissolves more salt, causing a lot of ice to melt, and the process still goes on.

Answer 2

Hey, sorry for the delayed response.

Hypothesis:

(Freshwater)  I think the ice cube will float to the top because it's less dense. The ice cube will then melt, and the food coloring/ water mixture will combine. I think the temperature on the top will be colder.

(salty water) I think with the salt, the ice cube will still float to the top, but it will melt faster. I think with the salt the temperature will have less of a difference from the top to the bottom.  

(saturated water) I think with the saturated water the ice will melt faster. I think the ice cube will still go to the top because it's less dense. I think with the saturated water the temperature will be the same.

Lab report:

(freshwater)

0 minutes - The ice cube is placed into the water and sinks to the bottom. Temp 60F, 60F

5 minutes - The ice is starting to melt, and you can see the coloring mix a little bit. Temp 50F, 40F

10 minutes - The ice cube is about halfway melted, and the overall coloring is starting to change. The ice cube is still at the bottom of the glass. Temp 50F, 35F

30 minutes - The ice cube has fully melted, and the water has almost fully mixed. Temp 40F, 35F

(salty water)

0 minutes - The ice cube is placed at the top and floats to the top. Temp 60F, 60F

5 minutes - The ice started to melt and is starting to show at the top of the glass. Temp 40F, 55F

10 minutes - About half/ most of the ice has melted sitting at the top. There’s little to no color differences through the rest. Temp 35F, 55F

30 minutes - The ice cube has fully melted with a melted layer at the top. There’s a small color difference throughout. Temp 35F, 40F

(saturated water)

0 minutes - The ice cube is placed and floats to the top. The ice starts to melt. Temp 60F, 60F

5 minutes - The ice begins to melt. There is no mixing seen and you can see a layer of melted ice at the top. Temp 35F, 55F

10 minutes - About half of the ice is melted and you can still see a layer at the top. There’s starting to be a slight color difference. Temp 30F, 55F

30 minutes - The ice is fully melted, and you can see a layer of melted ice at the top. The water has changed in color a small bit throughout. Temp 30F, 50F

Solution:

Fresh water -

With the ice cube and freshwater, the food coloring almost completely mixed. As the ice melted it didn’t all stay at the top of the glass. As the ice melted the top was way colder in the beginning then the bottom of the glass, but overtime the temperature went from a 15-degree difference to only a 5-degree difference.

Salty water -

With the salty water the ice cube melted at the top of the glass. With the salt the food coloring mixed but not as much as the freshwater. Some of the food coloring remained at the top of the glass with the melted ice. The temperature of the water started the same, but overtime as the ice melted at the top the top got colder. The biggest difference was 20-degrees but ended with a 5-degree difference.

Saturated water -

With the saturated water the ice melted at the top of the glass creating a melted ice pool. This made the food coloring mix even less. Most of the food coloring remained at the top. The temperature of the water started the same, but the top of the glass got a lot colder. Since the melted ice mainly stayed at the op this resulted in a difference of 25-degrees and ended with a difference of 20-degrees.

Answer:

This experiment suggests that as icebergs melt into the ocean the cold water stays at the surface.

I really hope this helps K12 students! Just PLEASE DON'T DIRECTLY COPY AND PASTE. I don't want you or me to get in trouble so please rephrase into your own words. Please mark brainliest, and I got a 15/15 on this assignment so I can guarantee the answers to be correct :)
