A gas was placed in a container at 300 k. if it is then heated at constant volume to 900 k, which statement/ statements correctly represent(s) the effect this would have on the kinetic energy of the gas molecules? i. kinetic energy will be halved ii. kinetic energy will double iii. kinetic energy will increase iv. kinetic energy will triple
Accepted Answer
The correct statements are II and III: kinetic energy will double and kinetic energy will increase. Here's why:
Kinetic Molecular Theory: The kinetic energy of gas molecules is directly proportional to their absolute temperature. This means that as temperature increases, the average kinetic energy of the molecules also increases.
Calculation: The temperature increased from 300 K to 900 K, a threefold increase. Since kinetic energy is directly proportional to temperature, the kinetic energy will also triple.
Important Note: While the kinetic energy
will
triple, it's not accurate to say that it will
only
triple. Any increase in temperature will result in an increase in kinetic energy.
