Which best represents a physical change?

Chemistry
1 answer:
Zinaida [17]3 years ago
4 0

Answer:

The answer I would go with is A formation of a new substance.

Explanation:

This is because physical change includes changes of state. Some could be changing from a liquid to gas or solid to gas. B is not even an answer that should be considered because it doesn't fit into the category. C and D represents some of the examples of the process of physical change. Like boiling, bubbling, melting, or freezing. So the best would be A.

Identity the step that is not part of the scientific method.
horrorfan [7]

Options:

conduct an experiment

form a hypothesis

draw a conclusion

state the cause

Answer:

'<u>State the cause'</u> is not part of the scientific method.

Explanation:

The scientific method has three wholistic steps:

  • Test the hypothesis
  • Make observations from the experiment to the hypothesis
  • Draw a conclusion or prediction from the experimental results.

A cause is neither a scientific term nor is it part of the  processes of experimentation.

I hope this was helpful.
