Use these facts on the heating and cooling curve of water in answering the following activities.

Write TRUE if the statement is correct but if it’s false, change the underlined word or group of words to make the whole statement true. Write your answer on a separate sheet of paper. 1. Dynamic equilibrium will only exist if the reaction is irreversible where the substances transition between reactants and products are at equal rates.arrow_forward
- Why does the temperature of a substance not change when the phase changes? 1.) The energy is going into breaking/forming intermolecular interactions, allowing for phase change 2.) The energy must be converted to another form of radiation before it can increase the temperature 3.) The temperature changes but not enough to be measured 4.) The matter absorbs all the energy into the covalent bonds of the molecule, preventing any temperature change.arrow_forward5.
