Students were conducting an investigation to see how the lid of a cup affects the temperature of the liquid inside the cup. The students will set up two identical cups, one with a lid and one without. They will use the same amount of water for each cup with the same initial temperature. After 30 minutes they will record the temperature of each cup to see which one had the most temperature change. Drag and drop each of the variables to their correct classification. Independent variable
Dependent variable
Controlled variable

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

your answer is c) plasma
