The temperature on the Celsius scale is $25^{\circ}C$. What is the corresponding temperature on the Fahrenheit scale in $^{\circ}F$?

What is the base of the absolute temperature scale?

$A$ Centigrade and a Fahrenheit thermometer are dipped in boiling water. The water temperature is lowered until the Fahrenheit thermometer registers $140\,^{\circ}F$. What is the fall in temperature as registered by the centigrade thermometer?

Maximum density of $H_2O$ is at the temperature .......... $^\circ F$.

$A$ thermometer bulb has a volume of $10^{-6} \,m^3$ and the cross-section of the stem is $0.002 \,cm^2$. The bulb is filled with mercury at $0^{\circ} C$. If the thermometer reads a temperature of $100^{\circ} C$, what is the length of the mercury column? (Coefficient of cubical expansion of mercury $\gamma = 18 \times 10^{-5} /{ }^{\circ} C$)

In the definition of 'calorie',one calorie is the heat required to raise the temperature of $1\ g$ of water through $1\ ^oC$ in a certain interval of temperature. The temperature interval is
