Which condition will cause the pressure exerted by a gas in a closed container to increase?

a. an increase in volume

b. an increase in temperature

c. a decrease in molecular movement

d. a decrease in the number of gas molecules

B

Pressure is force / area. The pressure of a gas in a container can be considered to be the force exerted on the area of the container by gas molecules. If the temperature is increased the gas molecules have more energy so collide with the walls more often and with more force causing pressure to increase.
