Which is the definition of heat? (1 point)
Heat is the absence of cold energy. The less cold energy an object has, the more heat it has.
Heat is the flow of energy between objects, which occurs by particles bumping into each other.
Heat is the flow of energy between objects, which occurs by particles traveling from one object to another.
Heat is a measure of how easily particles in an object can move. The easier that they move, the more heat an object has.

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 .
