Five hundred million years ago, basaltic lava flowed in an area now known as monticello, the historic home of thomas jefferson. some of this rock has since re-crystallized under intense heat and pressure and then has been eroded by wind and rain. the order of the rock cycle in this case is best described as a) metamorphic, igneous, sedimentary. b) igneous, sedimentary, metamorphic. c) igneous, metamorphic, sedimentary. d) metamorphic, sedimentary, igneous.

C) igneous, metamorphic, sedimentary

the answer

explanation:

the capillary tube was too close to the bottom of the beaker.

the ruler may have moved.

water got into the capillary tube.

the temperature was not allowed to equilibrate in the 2-4 minutes.

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.
