The statement that liquid water has a low specific heat is incorrect. In fact, liquid water has a relatively high specific heat capacity. The specific heat capacity of a substance is the amount of heat required to raise the temperature of one gram of that substance by one degree Celsius. The specific heat capacity of liquid water is 4.18 J/g°C, which is significantly higher than that of many other common substances such as metals and rocks. This means that water is able to absorb and release a large amount of heat without undergoing a significant change in temperature, making it an excellent coolant.
