Question
please show at least brief explanatin for your choice , 5 stars for correct and exlained solution
The pressure of a gas inside a closed, rigid container will increase when the gas temperature increases. The pressure of the gas increases because the density of the gas decreases rate of collisions of gas molecules with the surface increases. container expands in size when heated. gas molecules bond together to form more massive molecules. A gas in a sealed cylinder is heated from bottom of the cylinder. Which of the following does not increase as the gas is heated? the average number of gas molecules hitting the cylinder walls per second the average kinetic energy of the gas molecules the average speed of the gas molecules the average distance between the gas Molecules When a gas is heated in a closed container, the internal pressure increases. Which best describes the reason for the increase in pressure? The average kinetic energy of the gas molecules decreases. The potential energy of the gas increases. The average kinetic energy of the gas molecules increases. The potential energy of the gas decreases.
Explanation / Answer
11)
B is correct
pressure increses due to increased speed and it measns a faster rate of collision
12)
D) is correct as all others depends on velocty which is function of temperature
13)
C is coorect as due to KE only the velocuty increses which causes increase in pressure
