Question

question 6
raising the temperature of water requires a lot of energy due to its _
low heat capacity
high heat capacity
low boiling point
high melting point

Explanation:

Heat capacity is the amount of energy needed to change a substance's temperature. A high heat capacity means more energy is required for a temperature change. Water has a high heat capacity, so raising its temperature needs a lot of energy. Low heat capacity would mean less energy is needed (contradicts the question). Boiling point (temperature at which liquid turns to gas) and melting point (temperature at which solid turns to liquid) are not related to the energy needed to raise temperature (as per the question's context).

Answer:

high heat capacity
