Answer:
True
Explanation:
One of the strong proponent to support a hypothesis is its ability to be falsifiable. Also, a hypothesis must be testable. To truly test a hypothesis, one must be able to prove it wrong. If a hypothesis cannot be proven wrong, then it is a very good hypothesis and can be made a theory.

Answer:
Solids, liquids and gases all expand when heat is added
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ...
Answer:
V = 0.356 L
Explanation:
In this case, we need to use the following expression:
M = n/V (1)
Where:
M: molarity of solution (mol/L or M)
n: moles of solute (moles)
V: Volume of solution (Liters)
From these expression, we can solve for V:
V = n/M (2)
Now, replacing the given data we can solve V:
V = 8.9 / 25
V = 0.356 L
