Energy is released during which phase changes? check all that apply. boiling condensing depositing freezing melting subliming

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
