The temperature on a Fahrenheit temperature scale that is twice the temperature on a Celsius temperature scale is: (in $^{\circ} F$)

On a temperature scale $Y$, water freezes at $-160^{\circ} Y$ and boils at $-50^{\circ} Y$. On this $Y$ scale, a temperature of $340 \ K$ is (in $^{\circ} Y$)

What is the base of the absolute temperature scale?

What is the value of the fixed point on the standard (Kelvin) scale?

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

$A$ hypothetical thermometer reads $5^{\circ} C$ in melting ice and $99^{\circ} C$ at the steam point. What is the correct temperature in $^{\circ} F$ when this faulty thermometer reads $52^{\circ} C$?
