An experiment was carried out to find the height of a student. A motion sensor was
placed on the ground and the height of the room was measured to be 2.3 m. The
motion sensor was then placed on the student’s head and the measurement was
recorded as 0.8 m. What is the height of the student?

Tammy is making 5 batches of punch for the school's Spring Carnival. The recipe for one batch uses 1 liter of orange juice, 550 milliliters of lemon juice, 2.5 liters of soda water, and two 850 milliliter bottles of apple cider.

How much punch will she make?

Tammy will make  

L of punch.

Explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

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.
