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

In anomalous expansion of water, at what temperature is the density of water maximum?

If the temperature of a body increases by $30^{\circ}C$ on the Celsius scale,then the increase in temperature on the Fahrenheit scale is .... $^oF$.

Two absolute scales $A$ and $B$ have triple points of water defined to be $200\; A$ and $350\; B$. What is the relation between $T_{A}$ and $T_{B}$?

The triple point of water is

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?
