Hello there.
<span>6. The specific heat capacity of aluminum is 0.22 cal/g°C. How much energy needs to flow into 20.0 grams of aluminum to change its temperature by 15°C?

The answer for this question is Control Variable because it doesn’t change throughout the experiment.
Answer:
(wait tell someone els answers please)
Im pretty sure its A
Greater energy makes fast-moving water a greater force of erosion.
Then its acceleration must decrease, by the same factor as you increased the mass.
The PRODUCT of the (mass) times (acceleration) doesn't change.
It's equal to the force acting on the mass. (Newton #2: F = M·A.)
So, since the product has to remain constant, if you multiply the mass
by something, then the acceleration will divide by the same thing.
