$A$ 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?

The gas thermometers are more sensitive than liquid thermometers because

On a linear temperature scale $Y$,water freezes at $-160^{\circ}Y$ and boils at $-50^{\circ}Y$. On this $Y$ scale,a temperature of $340\,K$ would be read as........ $^{\circ}Y$ (water freezes at $273\,K$ and boils at $373\,K$).

The resistance of the platinum wire of a platinum resistance thermometer at an ice point is $5 \Omega$ and at steam point is $5.23 \Omega$. When the thermometer is inserted in a hot bath,the resistance of a platinum wire is $5.795 \Omega$. Calculate the temperature of the bath. (in $^{\circ} C$)

It is difficult to cook rice in an open vessel by boiling it at high altitudes because of

$A$ calorie is defined as the amount of heat required to raise the temperature of $1 \, g$ of water by $1^{\circ} C$. Under which of the following conditions is this defined?
