If the temperature of an object is $140^{\circ}F$,then its temperature in Celsius is ........ $^{\circ}C$.

On the Celsius scale,the absolute zero of temperature is at .......... $^\circ C$.

Which of the following figures represents the relation between Celsius $(C)$ and Fahrenheit $(F)$ temperatures?

The resistance of a thermometer is $100 \Omega$ at the triple point of water $(273 \ K)$ and is $300 \Omega$ at the melting point of gold $(873 \ K)$. The temperature at which the resistance of the thermometer is $200 \Omega$ is: (in $K$)

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?

The temperature at which the reading on the Fahrenheit scale becomes $90 \%$ more than the reading on the Celsius scale is: (in $^{\circ} F$)
