Question

Identify which statement below is a hypothesis, and explain why. How could you determine whether the hypothesis is correct?

a. Ocean water is too salty.
b. water heats faster if it contains salt.
c. Space probes have discovered small amounts of water on the moon.

Answer 1

The statement 'Water heats faster if it contains salt' is a hypothesis because it is a testable explanation. An experiment comparing the heating of saltwater and freshwater could determine its validity.

Step-by-step explanation:

The statement that qualifies as a hypothesis is: 'Water heats faster if it contains salt.' This qualifies as a hypothesis because it is a suggested explanation that can be tested experimentally to see if it holds true. To determine whether this hypothesis is correct, one could conduct an experiment where two samples of water, one with salt and one without, are heated under identical conditions to see which one reaches a certain temperature faster.

Answer 2

b.

I would heat 2 equal quantities of water, one containing salt and one without with equal conditions (container, heat source, etc) and compare the amount of time it takes to heat from an equal starting point to an equal finish point.
