Surface tension causes water to on surface like glass. Water molecules are to other water by a process called cohesion. Surfactants are used to break cohesion between water molecules, making surfaces wetter and allowing water to away dirt.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

it would be a gas formation

the maximum mass of nh3 is nh3 in grams
