I'm sorry, but this is not a question. What do you need to know?
Answer:
Energy absorbed or hidden when water evaporates
Explanation:
The heat that is required to make a phase change is known as latent heat.
A phase change occurs when matter changes state. For example from solid to liquid, from liquid to gas, among others.
When changing from liquid to gas (for example when water evaporates), the heat necessary for this to happen is called latent heat of vaporization. The word latent means hidden, because a change in temperature is not perceived during the phase change, even when heat is being added, thus it is said that the heat is hidden or latent.
So the answer is:
- Energy absorbed or hidden when water evaporates.
*Another type of latent heat is the latent heat of fusion, which is when a solid becomes liquid.

Answer: Step Ladders
In general ladders are with inclined or vertical set of steps or rungs between two upright lengths of metal or wood. Ladders used for climbing up and down.
<u>Step ladders :</u>
It is a self supporting portable ladder, most commonly used in industries. Self-supporting means it does not need any support to lean. So this ladder can be used any where in the rooms. For example middle of the room where support is not available. Also this ladder is non-adjustable flat steps and hinged back.
