when a solid such as ice begins to melt, heat energy is added. what is the function of this added heat energy? a to increase potential energy b to separate hydrogen atoms from oxygen atoms c to break the bonds between the individual water molecules d to add energy to the hydrogen bonds among water molecules
Answer
Brief Explanations:
When ice melts, heat energy is used to break the intermolecular forces (hydrogen - bonding is a type of intermolecular force) between water molecules, not to break the covalent bonds within water molecules (separating hydrogen and oxygen atoms). It doesn't increase the potential energy in the sense of adding energy to the hydrogen bonds but rather overcomes the forces holding the molecules in a solid - state.
Answer:
C. to break the bonds between the individual water molecules
