Answer:
I t hi ink the answer is b sorry if I'm wrong but yeah peeps
Evaporation is called a surface phenomenon because water molecules present on the surface of liquid are bonded weakly as compared to inner molecules and when temperature increase hydrogen bonding between molecules break .Due to this water molecules tend to evaporation so that's why evaporation called the surface phenomenon.
Avogadros Law if pressure is the result of collision, molecules colliding with the wall of the container and every time they collide they exert a force. pressure is the result of the force and area. if we add more gas particles you are going to see more collisions with the wall of container the gas particles will exert a greater over the same exact area. they have a directly proportional relationship. Pressure and volume, pressure=force/area, if we have a container with the same number of particles but of different particles, the smaller volume containers will have smaller area and more collision increasing pressure so they have an inversely proportional relationship. Pressure and temperature, pressure=Force/area force is going to change not the area, when we heat up the molecules up they end up moving faster colliding with the walls of the container more often exerting a greater force. now Volume and temperature, if we heat the gas particles, they move more rapidly gas expands!.

Explanation:
Amino acid functional groups refer to the amino (~NH3+) and carboxyl (~COOH) group bonded to the alpha carbon. At biological pH (~7.2) the carboxyl will become deprotonated to carboxylate (~COO-). Each amino acid also has a side chain (R group) that may also exhibit functionality.Aug 4, 2015
