Question

nick hypothesizes that wax has a higher melting point than chocolate. how can nick test his hypothesis?

a. heat equal masses of wax and chocolate and measure their temperatures when they start to melt.

b. use mohs hardness scale to test how easily wax and chocolate can be scratched.

c. heat samples of wax and chocolate and use a stopwatch to time how long it takes until they start to melt.

d. measure the volume and weight of samples of wax and chocolate and calculate their densities.

Explanation:

To test the hypothesis about melting points, one should heat equal - mass samples and measure the melting - start temperatures. Option B tests hardness, C measures melting time not melting point, and D calculates density not melting point.

Answer:

A. Heat equal masses of wax and chocolate and measure their temperatures when they start to melt.
