Which of the following would cause an increase in the pressure inside a sealed container of gas? A. an increase in the size of the container / B. removal of half of the gas / C. a leak in the container / D. an increase in temperature

The correct answer would be D. An increase in the temperature will result to an increase in the pressure inside a sealed container of gas. Temperature is directly related to the kinetic energy. More kinetic energy, more motion of the molecules thus more pressure on the container. This can also be seen in the ideal gas equation which is expressed as PV = nRT.
