A sample of solid candle wax is put into a pot on the stove. Heat energy is transferred to the wax at a constant rate by the burner on the stove. Match the segments on the graph to the correct description of what is happening to the wax. A-B

B-C

C-D

D-E

E-F

(match them)
melting
gasseous wax heating
solid wax heating
boiling
liquid wax heating

Explanation:

The temperature increases as each phase is heating. The temperature remains constant as each phase is changing to the next. The phases associated with increasing temperature are solid, liquid, gas — in that order.

A-B  solid wax heating

B-C  melting

C-D  liquid wax heating

D-E  boiling

E-F  gaseous wax heating

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.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
