A cylindrical metal rod of length $L_0$ is shaped into a ring with a small gap as shown. On heating the system
$x$ decreases, $r$ and $d$ increases
$x$ and $r$ increases, $d$ decreases
$x$, $r$ and $d$ all increase
Data insufficient to arrive at a conclusion
The rods of length $L_1$ and $L_2$ are made of materials whose coefficients of linear expansion are $\alpha _1$ and $\alpha _2$. If the difference between the two lengths is independent of temperatures
$0^o C$ $1\ gm$ ice is mixed with $100^o C$ vapor then what wiil be the final temperature ($^o C$)?
$2\,g$ of steam condenses when passed through $40\,g$ of water initially at $25\,^oC$. The condensation of steam raises the temperature of water to $54.3\,^oC$, ........ $cal/g$ is the latent heat of steam ?
Mercury is of ten used in clinical thermometers. Which one of the following properties of mercury is not a reason for this?
A constant volume gas thermometer shows pressure reading of $50 \,cm$ and $90 \,cm$ of mercury at $0^{\circ} C$ and $100^{\circ} C$ respectively. When the pressure reading is $60 \,cm$ of mercury, the temperature is ......... $^{\circ} C$
