Describe briefly how the volume of a given mass of water changes when it is cooled from 7 ^0 C to 1^0 C use the terms increase, decrease and maximum or minimum

physics
At what temperature is the density of water MAXIMUM ? Why does water have a maximum density ( Other liquids do not)

physics
A liquid expands on heating. Explain briefly how its density will change with rise in temperature

physics
liquids in general expand on heating but when water in an ordinary glass flask with a narrow neck is heated the level is found to first fall and then rise why ?
