Agas cylinder contains argon atoms (m=40.0 u). the temperature is increased from 286 k (13°c) to 362 k (89°c) (a) what is the change in the average kinetic energy per atom? ev (b) the container is resting on a table in the earth's gravity. find the change in the vertical position of the container that produces the same change in the average energy per atom found in part

(a). The change in the average kinetic energy per atom is .

(b). The change in vertical position is 2413 m.

Explanation:

Given that,

Mass = 40.0 u

The increased temperature from 286 K to 362 K.

(a). We need to calculate the change in the average kinetic energy per atom

Using formula of kinetic energy

Put the value into the formula

(b). The change in potential energy of the container due to change in the vertical position

We need to calculate the change in vertical position

Using formula of potential energy

Hence, (a). The change in the average kinetic energy per atom is .

(b). The change in vertical position is 2413 m.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
