A density glass bottle contains 44.25g of a liquid at 0(c) and 42.02 at 50(c). Calculate the real cubic expansivity of the liquid (Linear expansivity of glass=1.0*10^-5 K-1)?

Answer 1

You, Yemen, Omenala, Omen Stella, David Cameron ... wow! That's quite a personality conflict you have!

Pick a name and keep it. Continuing to switch names is childish and not useful. Continuing to do so can get you banned.

In addition, you'll find better help from tutors here if you indicate what YOU have done to answer each problem/question. Otherwise, they might think you are simply dumping your homework here, expecting others to do your thinking for you.

Answer 3

The linear expansivity of a metal P is twice that of another metal Q. When these materials are heated through the same temperature change, their increase in length is the same. Calculate the ratio of the original length of P to that of Q.
