Answer:
- Scientific question: does life exist on other planets?
- Non-scientific question: there are aliens that look like people?
Explanation:
A scientific question is a coherent question that can be used to develop a scientific hypothesis. Thus, a scientific question must be testable, verifiable, measurable and relevant to the topic of study. In the scientific method, the hypothesis is subsequently tested by experimental or observational procedures, where the results can be used to understand some particular aspect of the real world. On the other hand, a non-scientific question is a light conjecture which cannot be proved by using the scientific method.
Answer:
11690J
Explanation:
Use formula Q = mL
where:
Q = Energy (J)
m = Mass (g)
L = Latent heat of fusion for water (J/g) = 344J/g
Therefore:
Q = 35.0 x 344
Q = 11690J
