"The water becomes warmer."
<u>Remember</u>: Kinetic energy means how much, on average, a molecule is moving around. This is directly translated into heat. Therefore, the higher the kinetic energy, the more heat produced.
Answer : Hypothesis.
Explanation : Hypothesis is defined as the supposition or proposed explanation which can be made on the basis of limited available evidence as a starting point for further investigation. Here, in this question the proposed explanation for the changing colors of the sky is an example of a hypothesis.
A hypothesis has to be supported with scientific experiments which are reproducible by several experiments and test results have to be valid to be called as a scientific theory.
Answer:
The volume is 10,92 L
Explanation:
We use the formula PV=nRT:
V= (nRT)/P
V= (0,500 mol x 0,082 l atm/K mol x 799 K)/3,00 atm
<em>V= 10,91966667 L</em>
