On a cool morning chelas breath can form a cloud when she breathes out which changes of state are most responsible for sheila seeing her breathe this way

Vaporization and condensation

Explanation:

The changes of state are more responsible for sheila seeing breathe are condensation and Vaporization.

When we breathe out on cold morning, the moisture in our breathe vaporizes, then the cold air outside condenses the water vapor into tiny droplets of liquid water and ice.

We see this as clouds.

Condensation is the process of conversion of a gas into liquid and vaporization is the process of converting liquids into gas or vapours.

Some solid substances, for example camphor, get vaporized to gaseous state without passing through the liquid state.

This process is called sublimation.

The substance changes from a gas to a liquid is referred as Condensation and  the substance changes from a liquid to a gas is referred to as Vaporization.

Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
