[06.01]you have 500 grams of water at 80° celsius. you want to lower the temperature of the water to as close to 60° celsius as possible. which of the following would get the 500 grams of water the closest to 60° celsius?

The heat lost by the 80 deg.C solution would equal the heat gained by the colder solution, and the final temperature would be 60 deg.C. x is the amount of colder solution added and y is the initial temp of the colder solution.

Heat lost by 80 deg.C solution = (500 g)(1.00 cal/g C)(80 deg.C - 60 deg.C) = 1000 cal

Heat gained by colder solution = (x)(60 - y)

By evaluating further, we will arrive at adding 100 grams of 50° Celsius water. This satisfies to the problem above.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
