Two substances, a and b, of equal mass but at different temperatures come into thermal contact. the specific heat capacity of a is twice the specific heat capacity of substance b. which statement is true of the temperature of the two substances when they reach thermal equilibrium? (assume no heat loss other than the thermal transfer between the substances.)

the answer is c i believe

what are the statements

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.
