Korolek [52]
Evaporation occurs <span>when water absorbs 2260 Joules of heat energy per gram.  It is </span><span>process by which water changes from a liquid to a gas or vapor.</span> It takes energy for the molecules to break those bonds (to overcome the bonding forces). This energy is the latent heat of vaporization. 
<span>
Water requires the  addition of 2260 Joules of heat energy for every gram of water that evaporates (vaporizes). The heat energy that is required to change water into vapor is called the latent heat of vaporization.</span>

Why might material need energy to move through the cell membrane
bagirrra123 [75]

Answer:

Some transport requires energy.

Not all materials that move in and out of a cell can do so by diffusion. For cells to carry out life functions, materials must often move from areas of low concentration into areas of high concentration. This process of moving materials against a concentration requires energy.

Please said thanks
