A faulty thermometer has its fixed points marked $5$ and $95.$ If the temperature of a body as shown on the Celsius scale is $40,$ then its temperature shown on this faulty thermometer is

The reading of air thermometer at $0 °\mathrm{C}$ and $100 °\mathrm{C}$ are $50 \mathrm{cm}$ and $75 \mathrm{cm}$ of mercury column, respectively. The temperature at which its reading is $80 \mathrm{cm}$ of mercury column is

A difference of temperature of $25°\mathrm{C}$ is equivalent to a difference of 

The absolute zero, i.e., temperature below which is not achievable, is about

The temperature of a body on kelvin scale is found to be $x \mathrm{K}$. When it is measured by Fahrenheit thermometer, it is found to be $x° \mathrm{F}$, then the value of $x$ is

The thermal capacities of two bodies are in the ratio $1:4$. If the rates of loss of heat are equal for the two bodies under identical conditions of surroundings, then, the ratio of rate of fall of temperature of the two bodies is,

Water takes longer time to boil than mercury because water has.............

If a liquid takes $30 \mathrm{s}$ in cooling from  $95°\mathrm{C}$ to $90°\mathrm{C}$ and $70 \mathrm{s}$ in cooling from $55°\mathrm{C}$ to $50°\mathrm{C}$, then the temperature of the room is:
