b.) it has a very high melting point.
c.) it is formed when atoms share electrons in a chemical bond.
d.) it can also be called a molecule.

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

catya your not at all which answer i've seen you do this on another question!
