Suppose That Water Is Used in a Thermometer Instead of Mercury

question 23

Multiple Choice

Suppose that water is used in a thermometer instead of mercury. If the temperature is at 4°C and then changes, why can't the thermometer indicate whether the temperature is rising or falling?

• A)The water molecules will be a mixture of ice and water, and a change in temperature will only change the proportions of its phases.
• B)The water molecules are moving too slowly to be able to indicate a change.
• C)Water is most dense at 4°C. The water in a water-filled thermometer at 4°C would expand as the water was cooled or heated.
• D)Since water has such a high specific heat capacity, it will take a lot of energy to be able to see a change in the thermometer.
