Jasmine
Tasha
Based on the rankings provided by each student, the correct ranking of potential energies from lowest to highest is:
1. Tasha: solid, liquid, gas
2. Lucas: solid, gas, liquid
3. Jasmine: gas, solid, liquid
4. Henry: gas, liquid, solid
Therefore, Tasha is the correct student.
We would need to see the rankings provided by each student in order to determine who is correct.
Student Name Potential Energy Rating (lowest to highest)
Henry gas, liquid, solid
Jasmine gas, solid, liquid
Lucas solid, gas, liquid
Tasha solid, liquid, gas
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 increases, the kinetic energy of the water molecules decreases.
As the temperature increases, the kinetic energy of the water molecules decreases.
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 amount of ice added increases, the change in temperature increases.
Based on the given information, the conclusion that can be drawn from the results is:
As the temperature decreases, the kinetic energy of the sample increases.
