Answer:
Explanation:
Phase changes have to happen at a specific temperature. During a phase change, the energy is used to make the change happen, instead of raising the temperature.
On a graph, a constant slope, or in this case temperature, is a flat line. On this graph, the flat lines are at B and D.
There is no answer including B, but there is for D.
Choice D: <u>During the time labeled D, when the temperature stays the same</u> is correct.

Why do u keep making this question?
Answer: What do you mean with "successful"?
Explanation: First of all, if you need to established the fact that an experiment has been successful, it needs to be viable. And in order to be viable, it has to be practical.
Second thing, are we really talking about a "planet" ? Nevermind.
Life index, grade of utility/usefulness, scale of danger to other species, adaptability, aggressiveness. These are just a few blanks that your experiment has to have on <u>POSITIVE</u>.
Predicting a result it´s almost impossible without these parameters.
Let me know if you want me to help you a bit more.
