There is a 43-cubic-meter ethylene storage tank, with 5 cubic meters of ethylene remaining inside at a pressure of 12 Kg. Now, ethylene needs to be transferred from a tank truck into this storage tank. First, the storage tank and the tank truck need to be connected, and then the pressure inside the storage tank is reduced to 3 Kg. How much ethylene is left in the storage tank, and how much ethylene has been transferred from the storage tank to the tank truck?
You can use a balance to do it – weigh an empty vehicle once and a loaded vehicle once, and the data will be available.
This is a theoretical calculation problem related to the density of gases at different pressures as well as to temperature. It is necessary to find the density of gases at 12 and 3 kilograms of pressure at normal temperatures, and this can be determined through calculations.
