Question

Jenny measures the temperature inside a cave to be 30°C. The temperature outside the cave is about 80°C warmer.

How does the kinetic energy of the air molecules inside the cave compare to the kinetic energy of the air molecules outside the cave?​

Answer 1

Answer:

The temperature outside the cave is about 30°C warmer. How does the kinetic energy of the air molecules inside the cave compare to the kinetic energy of the air molecules outside the cave? The kinetic energy of the air molecules inside the cave is. the kinetic energy of the air molecules outside the cave.

Answer 2

Kinetic Energy is basically the rapid movement of the air molecules.

Remember this technique:-

Smaller the space, lesser the temperature and hence less activity by the gas particles. Hence, lesser the kinetic energy.

This derives :-

Temperature is directly proportional to kinetic energy.

So, the temperature inside the cave was less, so the kinetic Energy was less.

On the other hand when the temperature increases ie 30°C warmer, the activity rate increases and hence the kinetic energy increases.

Kinetic Energy of air molecules inside the cave < Kinetic energy of air molecules outside the cave ..
