How warm would 560 mL of water be after it gains 14.5 kJ of energy from a starting temperature of 25.6 °C?

Yes it would be a physical change.

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Ithink the answer is d

Answerit is not a suspension or colloid mixture, it is a solution mixture;
