Question

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. Heat samples of wax and chocolate and use a stopwatch to time how long it takes until they start to melt.
D. Use Mohs Hardness Scale to test how easily wax and chocolate can be scratched.

Answer 1

B because that would be the equal choice

Answer 2

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

To test his hypothesis, Nick should heat equal masses of wax and chocolate and measure their temperatures when they start to melt.
