student is investigating which type of sugar would dissolve fastest in hot tea- a sugar cube or granulated sugar. Which hypothesis should the student use for their investigation?

A.
It doesn't really matter. Both of them are sugar with the same chemical formula.

B.
Granulated sugar has more surface area than sugar cubes and will dissolve faster.

C.
Granulated sugar has less surface area than sugar cubes and will dissolve faster.

D.
Cubes have more surface area and will dissolve faster.

Construct the hypothetical phase diagram for metals a and b between room temperature (20c) and 700c, given the following information: * the melting temperature of metal a is 480c. • the maximum solubility of b in a is 4 wt% b, which occurs at 420c. • the solubility of b in a at room temperature is 0 wt% b. • one eutectic occurs at 420c and 18 wt% b–82 wt% a. • a second eutectic occurs at 475c and 42 wt% b–58 wt% a. • the intermetallic compound ab exists at a composition of 30 wt% b–70 wt% a, and melts congruently at 525c.• the melting temperature of metal b is 600c. • the maximum solubility of a in b is 13 wt% a, which occurs at 475c. • the solubility of a in b at room temperature is 3 wt% a.
