Which of the following situations is accurate regarding the transfer of heat?
a hot cup of coffee transfers heat to cold hands.
ice cubes in a glass lose heat to the warm soda.
thermal energy from the refrigerator is transferred to a bowl of hot soup.
an open door on a freezer cools a warm room.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

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.
