Increase in temperature of a gas filled in a container would lead to :(1) Increase in its mass(2) Increase in its kinetic energy(3) Decrease in its pressure (4) Decrease in intermolecular distance |
|
Answer» Due to increase in temperature of gas in container ..pressure in container will increase But for gas container is closed and hence no change in volume The correct option is (2) Increase in its kinetic energy. Explanation: Increase in temperature would lead to the increase in kinetic energy of gas (assuming far as to be ideal) as U = F/2 nRT Hence energy increases as the temperature is rose . It increases the activity o the molecule as they gain any energy. which in case here is the heat energy. The rise in temperature increases the vibrational energy of the molecule resulting in the increased movement of the atoms or molecules. In turn they will collide with surface walls and it will impart more energy to atoms or molecules hence increasing the overall kinetic energy of the atoms or molecules. |
