The pilot of a Boeing 767 determines that a total of 22,300 kilograms of jet fuel is needed to fly from Montreal to Edmonton. A floatstick check finds that there is 11,133 litres of fuel already in the tanks. How much fuel, expressed in litres, must be added to the tanks? The density of jet fuel varies with temperature. For the prevailing conditions take the density of the jet fuel to be 0.803 kg/L or equivalently 1.77 lb/L.
A cold wave in the US brings temperature to -53 °C. A cold air mass, known as the polar vortex, passed through the United States in January 2019 and caused the temperature to reach -53 °C. Several states declared an emergency, while Chicago and North Dakota experienced -30"C and -37"C, respectively. It can be said that the lowest temperature recorded, in Kelvin, by the Chicago thermometers was:
