Here's why:

* High Specific Heat: Water actually has a *high* specific heat. This means it takes a lot of energy to raise the temperature of water. This property is what makes water an excellent coolant.

* Why high specific heat is important for cooling: When water absorbs heat, its temperature rises relatively slowly. This allows water to absorb a significant amount of heat without drastic temperature changes.

Let's address the other statement:

* Ice is less dense than liquid water: This is true. That's why ice floats! This is an unusual property for most substances.

In summary: The statement about water's low specific heat being the reason for it being a poor coolant is incorrect. Water's high specific heat is what makes it an effective coolant.
