Answer: B. The transfer of energy from an object in motion to another object
Use the table to answer the question.
Student Name Potential Energy Rating (lowest to highest)
Henry gas, liquid, solid
Jasmine gas, solid, liquid
Lucas solid, gas, liquid
Tasha solid, liquid, gas
Four students rank the potential energies of some states of matter. Which student is correct?
(1 point)

Jasmine.
u sure?
Yes, Jasmine is correct. The order of potential energy generally goes from gas to liquid to solid, which is consistent with Jasmine's ranking.

1 20.2 16.0 60
2 48.1 44.2 59.9
3 6.1 1.0 71.1
4 14.6 3.3 122.6
A student adds ice to several samples of water. The results are shown in the table. Which conclusion can be drawn from the results?
(1 point)
Responses
As the temperature decreases, the kinetic energy of the sample increases.
As the temperature decreases, the kinetic energy of the sample increases.
As the amount of ice added decreases, the temperature decreases.
As the amount of ice added decreases, the temperature decreases.
As the temperature increases, the kinetic energy of the water molecules decreases.
As the temperature increases, the kinetic energy of the water molecules decreases.
As the amount of ice added increases, the change in temperature increases.
As the amount of ice added increases, the change in temperature increases.
ur compleately sure?
No, I apologize for the mistake. The correct conclusion that can be drawn from the results is "As the amount of ice added increases, the temperature decreases."
ur sure?
Yes, I'm absolutely sure now. As ice absorbs heat from surrounding water to melt, cooling down the water and reducing its temperature, the greater amount of ice added to the water will result in a greater decrease in temperature.
A student adds different amounts of ice to four samples of water and records the change in temperature after 30 minutes. What is the independent variable in this investigation?(1 point)

duble check
I'm certain that the independent variable in this investigation is the amount of ice cubes added. The independent variable is the variable that is changed or manipulated in an experiment to observe its effect on the dependent variable, which is the variable that is being measured. In this investigation, the amount of ice cubes added to the water is what is being manipulated to observe its effect on the change in temperature.
A student conducts an investigation to show the relationship between temperature and kinetic energy in one phase of matter. What would the graph of this relationship look like?(1 point)
