What happens to a gas that is enclosed in a rigid container when the temperature of the gas is increased?
a. the gas particles move faster and collide more frequently, which causes an increase in pressure.
b. the gas particles move slower and repel one another, which causes a decrease in pressure.
c. the gas particles expand and take up more space, which causes an increase in pressure.
d. the gas particles become smaller and take up less space, which causes a decrease in pressure.

A. the gas particles move faster and collide more frequently, which causes an increase in pressure.

Increasing temperature increases the energy of the gas, which causes the kinetic energy of the molecules to increase.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
