MCAT Question of the Day


  • Q:

    A researcher pumps a known gas into an empty cylinder, compressing the gas, and, as a consequence, increasing the temperature of the cylinder. In order to determine the amount of gas pumped into the cylinder, which of the following methods would be most effective?

     

    A

    use a pressure gauge and calculate the amount of gas based on the pressure and the known volume

    B

    measure the difference in mass before and after filling

    C

    measure the change in temperature before and after filling

    D

    use an ultrasonic device to measure the density of the gas inside the cylinder
