Mercury is of ten used in clinical thermometers. Which one of the following properties of mercury is not a reason for this?
The coefficient of the thermal expansion is large
It is shiny
It is a liquid at room temperature
It has high density
Two thermometers $X$ and $Y$ have ice points marked at $15^o$ and $25^o$ and steam points marked as $75^o$ and $125^o$ respectively. When thermometer $X$ measures the temperature of a bath as $60^o$ on it, ........ $^oC$ would thermometer $Y$ read when it is used to measure the temperature of the same bath ?
Heat required to melt $1\,gm$ of ice is $80\, cal$. A man melts $60\, gm$ of ice by chewing it in one minute, his power is ........ $W$
If a bimetallic strip is heated it will
If the volume of a block of metal changes by $0.12\%$ when it is heated thrugh $20\,^oC$, the coefficient of linear expansion (in $^o{C^{ - 1}}$) of the metal is
A glass flask of volume one litre at $0\,^oC$ is filled, level full of mercury at this temperature. The flask and mercury are now heated to $100\,^oC$. How much mercury will spill out, if coefficient of volume expansion of mercury is $1.82 \times 10^{-4}/^oC$ and linear expansion of glass is $0.1 \times 10^{-4}/^oC$ ? ............ $\mathrm{cc}$
