Most ionic compounds tend to be classified as select one:
a. fats
b. proteins
c. sugars
d. salts

Temperature and kinetic energy are proportional. a) adirectly b) directly c) indirectly

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
