This is a very good forum for learning to take place considering the fact that no man is an island of knowledge; we can never know it all and as such we need to learn from others. The purpose of this thread is to ask and answer questions on myriad of topics in physics, chemistry, biology nd probably mathematics and other science subjects. So the floor is now opened, throw in questions and let's discuss the solution. Post utme candidates, we are you?

Try mobilise utme candidates and u can also start dropin questions.

K. A substance starts to melt at 75degrees and melts completely at 78 degrees all in Celsius. What is d melting point

That question is simple enough to confuse me. Is the ans. 75? Btw, is that a post utme question? Post utme questions should be asked pls so that those of us who dont have them can know what they look like.

I think it's 78, is it?

If 21g of alcohol of density 0.7gcm is mixed wit 10g of water, what would be the density of the mixture?

Oh! deary me, there was me thinking the melting started @75℃. but seriously state the answer coz we are here 2 learn after all.

The answer to that question is 0.775gcm, approximately 0.8gcm

As for d first question, I don't really know d ans. Arosog, u'r right but explain how u got d answer.

please explain how u got thé answer......enough of lying and guessing.....
