Three thermometers are placed in a closed insulated box and are allowed to reach thermal equilibrium. One is calibrated in Fahrenheit degrees, one in Celsius degrees, and one in Kelvins. The Celsius thermometer reads -40° C and the Kelvin thermometer reads 233 K. Which one of the following statements is necessarily true?
The Kelvin thermometer should read -233 K.
The Kelvin thermometer should read -313 K.
The Fahrenheit thermometer must read -40° F.
If the water were found within the box, it must be in the liquid state.
If the temperature of the contents is increased by 10° C, the reading on the Kelvin thermometer should increase by 273 K.
