Atoy boat is floating in a large metal bucket. if you build a fire under the bucket, how the heat will transfer from the fire to the boat?

a. water molecules in the bucket will transfer the heat.
b. metal molecules of the bucket will transfer the heat.
c. surrounding air molecules will transfer the heat.

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.

answer: they produce more slow than unicellular organisms.
