    Sound propagates by transferring energy from one particle of the medium to the other. So when the medium particles will be close to each other (i.e. density of the medium is increased) the energy transfer will be faster and speed of sound will increase (this we see as speed of sound is zero in...

    another question when we make a solution of two miscible liquids the boling point of the solution is effected...now ignore that whether it increases or decreases but the whole sol. has a uniform boiling point...if it is so then how we will perform the process of fractional distillation????

    hey...i did o levels and thn opted for fsc...i am struggling with a question...can u guys hlp me?? we read that in solids speed of sound is greater cz its density is greater...but this formula v=E/density says that velocity is inversely proportional to density!!!!can u pls hlp me out??
