Question 40
F

A student measures the specific heat capacity of water. The water near the heater becomes warmer than water farther away. Which change improves the temperature measurement, and why?

[1]
A

Add more water; this makes its temperature more uniform.

B

Stir the water; this makes its temperature more uniform.

C

Touch the heater with the thermometer; this gives mean water temperature.

D

Remove insulation; this makes its temperature more uniform.
