A centigrade and a Fahrenheit thermometer are dipped in boiling water. The water temp is lowered until the Fahrenheit temp. register $140^o$. What is the fall in the temperature as registered by centigrade thermometer ....... $^oC$
Steam at $100\,^oC$ is more dangerous than the same mass of water at $100\,^oC$ because the steam
The coefficient of apparent expansion of liquid when determined using two different vessels $A$ and $B$ are $\gamma _1$ and $\gamma _2$ respectively. If the coefficient of linear expansion of the vessel $A$ is $\alpha $, then coefficient of linear expansion of $B$
