How is thermal energy transferred between two objects that are at different temperatures? Group of answer choices

Heat flows from the object that has more thermal energy to the object with less thermal energy.

The object at a lower temperature pulls heat from the warmer object.

Heat flows from the warmer object to the cooler object until they reach the same temperature.

Heat flows back and forth between the two objects untl they reach the same temperature.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
