Give the name of the instrument that measures temperature. Write the freezing and boiling points of water in $^oC$,$^oF$,and $K$.

An ideal thermometer should have

$A$ Celsius and a Fahrenheit thermometer are dipped in boiling water. The temperature of water is lowered until the Fahrenheit thermometer shows $140^{\circ}F$. What is the fall in temperature on the Celsius thermometer (in $^{\circ}C$)?

The phenomenon of superconductivity is observed at a temperature of $95 \ K$. The corresponding temperature on the Fahrenheit scale is ...... $^\circ F$.

Water has maximum density at

Two thermometers $X$ and $Y$ have ice points marked at $15^{\circ}$ and $25^{\circ}$ and steam points marked as $75^{\circ}$ and $125^{\circ}$ respectively. When thermometer $X$ measures the temperature of a bath as $60^{\circ}$ on it,what would thermometer $Y$ read (in $^{\circ}C$) when it is used to measure the temperature of the same bath?
