1. Water has a high specific heat capacity, meaning it requires a large amount of energy to change its temperature. This can make it less sensitive as a thermometric substance compared to other substances with lower specific heat capacities.
2. Water has a relatively narrow temperature range over which it remains in a liquid state, making it less suitable for measuring extreme temperatures.
3. Water has a high surface tension, which can affect the accuracy of temperature measurements as it can cause the formation of meniscus in the thermometer.
4. Water has a tendency to evaporate at higher temperatures, leading to inaccuracies in temperature readings.
