The correct answer is Hypothesis.

Here's why:

1.A hypothesis is a testable statement or prediction about how two variables are related. In this case, the statement predicts that increasing the temperature of water will allow it to dissolve more salt. This is a specific, testable prediction that can be experimented on and verified through observation and experimentation.

2.A theory is a well-substantiated explanation of a broad range of phenomena that is supported by a large body of evidence and can be tested through many experiments. This statement does not explain why the temperature affects the solubility of salt ...
