Is steam and mist the same?

Steam is water in a gas phase, while mist, or fog, are small droplets of water in the condensed phase, but small enough to be kept in the air by thermal Brownian motion. It is an invisible gas, and contains a large latent energy which is released when the steam condenses into droplets.

Is fog water vapor?

Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets. Water vapor, a gas, is invisible.

How does fog form over water?

Fog that forms over water is commonly referred to as sea fog or lake fog. It forms when warm, moist air flows over relatively colder waters. Fog is common along the U.S. Pacific coastline year round because the water is typically much colder than the nearby land.
