is there any kind soul who can help me? Thanks!

Homework Statement We propose to study simple processes of liquid alcohol. At T_1, the molar volume of alcohol is V_1 and its molar heat capacity at constant pressure is C_p,m. We assume that its isobaric coefficent of thermal expansion a, and the isothermal compressibilty coefficient B are...

thanks a million for the numerous replies, i finally begin to understand it and i even learned a new concept with the balloon in the car:biggrin: and...also sorry for the inconvenience caused by posting it in the wrong section intially and has it to be moved to the correct section

I have some questions which i can't seem to answer and understand. Here goes: Imagine a bee flying inside a moving train moving at a constant velocity in one particular direction. the bee is flying in mid-air and is not in contact with any of the train parts. qns 1: does the bee need to...

let me try for qns 1: Choose a scale for ur ruler like 1cm of ruler:10ft/20ft/30ft. Choose what you deem fit. Then, draw the diagram using ruler and protractor Join starting point to ending point and you should get ur displacement. qns 2: try the tactic from 1 qns 3: tactic from 1...

maybe the threadstarter want to know why is the equation \nu \lambda = c ?

Ok, i think i got it. Thanks for your help! Will there be a case where both densities are the same? In that case, will there be a rise of water level?

hint: why don't you try taking some coins from here and there and weigh them together? Your grouping is correct but grouping sometimes is an unwanted restriction:smile:

ok, so the symbol \Delta m_i u have used in the previous post is actually the vol. of water that will be produced by the little bit of ice when it melts and not the vol. of water displaced by the ice? Then, can i say that the vol. of ice before it melts is different from the vol. of water if...

I still don quite get it...When the ice is only partially submerged on the water, is e total volume of ice=the volume of water displaced by the ice? But, if we try to calculate the vol. of water displaced, we will use the vol. of ice which is submerged in the water as the vol. of water...

This is not actually a question from my tutorial but it stemed out from there. So, here it goes: Consider a block of ice partially submerged on water. It is floating, so by the principle of floatation and Archimedes' Principle, the weight of water displaced equals to the weight of the block of...
