Question 2 (1 point)
A cold glass of water collects water droplets on the outside on a hot summer day.
What is the best explanation for this?
The water vapor in the air releases energy to the cold water in the glass causing
the vapor to become liquid that collects on the sides of the glass.
The water vapor in the air gains energy and collides against the sides of the cold
glass resulting in water droplets forming on the sides of the glass.
The cold water in the glass heats up and then this water collects in droplets on
the sides of the glass.
The cold water in the glass releases energy to the water vapor in the air causing
it to collect on the outside of the glass.

The water vapor in the air releases energy to the cold water in the glass causing

the vapor to become liquid that collects on the sides of the glass.

Explanation:

Matter exist in solid, liquid and gaseous states. The energy of particles constituting each state of matter differs. In the gaseous state, the particles that compose matter are highly energetic and move at high speeds. Liquid particles possess lower energy and solid particles are the least energetic.

When water vapour in air comes in contact with a cold glass of water, heat exchange occurs. The energetic gas particles of water vapour looses energy to the cold water particles. This causes the water vapour outside the glass to condense to liquid and collects outside the glass.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

a corroding iron, if that's one of your choices
