The prompt asks about the meaning of water having a high specific heat, so we evaluate each statement in turn.
Option 1: 'Water can only heat up to a certain temperature.' This is incorrect because water can continue to heat as energy is added, up to its boiling point, and the statement misstates the concept of specific heat which is about the rate of temperature increase, not an absolute ceiling.
Option 2: 'Water grows hot very quickly compared to most other substances.' This is the opposite of what high specific heat means. A high specific heat implies slower temperature rise, not rapid heating, so this claim is false.
Option 3: 'Water freezes easily compared to most other substances.' The ease of freezing involves phase change properties and the freezing point, not the specific heat capacity in the heating context. This statement conflates phase behavior with specific heat, making it incorrect.
Option 4: 'Adding energy changes the temperature of water slowly compared to most other substances.' This aligns with the definition of high specific heat: it takes more energy to raise the temperature by a given amount, so the temperature rises slowly relative to substances with lower specific heat. This statement correctly captures the concept.
Option 5: 'The boiling point of water is very low compared to most other substances.' Water's boiling point is not particularly low (it is 100°C at 1 atm), and the statement misrepresents what high specific heat refers to. Boiling point is a separate property, not the same as specific heat.
In summary, the only statement that accurately reflects the meaning of water having a high specific heat is Option 4, since it describes the slower temperature change per unit of added energy compared to other substances.
