Devora tested two engines. As each engine's rotation got faster, its temperature increased at a constant rate.
The first engine's temperature (in degrees Celsius) as a function of its rotation speed (in cycles per second) is given by the following table of values:
The Table is for the first engine below
For the second engine, the graph is below
The temperature of which engine increased more for each increase of 1 cycles per second?
Choose 1
(Choice A)
A
The first engine
(Choice B)
B
The second engine
(Choice C)

Which engine was hotter when it rotated at 20 cycles per second?
Choose 1
(Choice A)
A
The first engine
(Choice B)
B
The second engine
(Choice C)
