A local recreation center has received funding to build a swimming pool. After construction, the center will be
responsible for all costs associated with pool operation. As a result, the center must
consider a variety of design
options, including pool size, location, and heating.
What happens to water molecules in a pool as they absorb energy?
A. The molecules begin to move more slowly
B. The rate of collision between molecules increases
C. The molecules occupy less volume
D. The kinetic energy of the atoms decreases

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

you need to have a picture of the atom that way we can answer it

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
