A closed, rigid container with a given mass of helium gas is heated until the temperature is doubled. Which of the following statements is TRUE? A The pressure of the gas is unchanged, because there is no relationship between temperature and pressure. The pressure of the gas is unchanged, because helium gas is lighter than the air outside the container. The pressure of the gas also doubles, because temperature and pressure are directly related. D. The pressure of the gas is halved, because temperature and pressure is inversely related. ©2021 Iluminate Education TM, Inc.
