A glass cylinder can contain m=100 gms of mercury at a temperature of T=0 degree celc. at T1= 20 degree celc, the cylinder can contain m1=99.7 g of mercury. in both cases, temperature of mercury is assumed to be equal to that of cylinder. using this data, find coefficient of linear expansion of glass where coefficient of volume expansion of mercury is 18 x 10^-5

The difference in cubical expansion of mercury and glass is 0.3g/(density of mercury).. Can you do it further?

anonymous · Answer

can you just explain what happens?
according to me, initially, the glass wud be filled with mercury upto the brim..later after heating, some mercury will flow down and hence mass of mercury is changed in the glass jar. right?

ujjwal · Answer

right.

okay il try it. thanks...
