Chemical energy is converted to thermal energy.
The correct answer is c because enzymes increase the rate of all biochemical processes
1) You need to get volume of both temperatures by using first attached formula V= Mass/Density

2) Using the second formula you get the height of 0 degree

(radius in cm is

3) Then with h1 you can easily get the height of 25 degrees
Subtract 943.5 cm - 939.2 cm, and obtain a rise in mercury height of 4.3 cm
