The co-efficient of real expansion of a liquid is 7×10−4/oC. The co-efficient of linear expansion of the vessel is 1×10−5/oC. The co-efficient of apparent expansion of the liquid is :
A liquid with co-efficient of volume expansion (γ) is filled in a container of material having co-efficient of linear expansion (α). If the liquid overflows on heating, then
The co-efficient of real expansion γr of a liquid is 5 times the co-efficient of linear expansion of the material of the container in which the liquid is present. The ratio of the co-efficient of apparent expansion and real expansion of the liquid is:
For a liquid, when heated in a vessel it is found that γa=67γr. The co-efficient of linear expansion of the vessel is :
The co-efficient of linear expansion of glass is 8×10−6/oC and the co-efficient of real expansion of mercury is 180×10−6/0C. The co-efficient of apparent expansion of mercury in glass vessel is :
