Question

(NO LINKS) Nick hypothesizes that wax has a higher melting point than chocolate. How can Nick test his hypothesis?

A.
Measure the volume and weight of samples of wax and chocolate and calculate their densities.
B.
Heat equal masses of wax and chocolate and measure their temperatures when they start to melt.
C.
Use Mohs Hardness Scale to test how easily wax and chocolate can be scratched.
D.
Heat samples of wax and chocolate and use a stopwatch to time how long it takes until they start to melt.

Answer 1

Actually the real answer is C. Nick should use Mohs hardness scale to test how easily the wax and chocolate can be scratched.

Answer 2

The answer is D

Step-by-step explanation:

You can test whether the wax or the chocolate will melt faster in the same temperatures to prove Nick's hypthesis.

Hope this helps!
