Sometimes matter behaves in unexpected ways. For example, some people claim that hot water will freeze into ice cubes faster than cold water. Could this be true? Describe an experiment that you could perform to test this question. Be sure to include the materials, procedure, and data you would collect.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
