2. which of the following is true about conduction?
it is heat transfer through direct contact
it can only occur in a liquid
it is heat transfer in currents through a liquid
it is heat transfer as a form of light

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.

the right answer is c i just did the question.
