What causes beads of moisture to form on the outside of a cold drinking glass? a. water vapor in the air gains thermal energy from the cold glass surface. b. water vapor in the air condenses into a liquid on the cold glass surface. c. the melting ice in the drink causes some liquid to spill over. d. water vapor in the air has less thermal energy than water in the glass.

B. Water vapor in the air condenses into a liquid on the cold glass surface

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

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.
