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

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?

$A$ 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?

In the absence of an atmosphere,the average temperature on the surface of the Earth would be . . . . . . .

Explain which property of liquid is used with temperature to measure it in a thermometer and how a thermometer represents it.

The temperature of a substance increases by $27^{\circ}C$. On the Kelvin scale,this increase is equal to ........ $K$.
