Answer 16

Here at OpenStudy we value the learning process, which means refraining from telling the user asking the question the direct answer. Instead you could have asked him which one he thought was correct and then state whether you agreed or not.

Answer 17

And yes, I know B. was the correct answer, but do you understand why? @whatsupneedhelp

Answer 18

Well, wouldn't different masses freeze at different times?
