Answer:
C. Plug the unknowns into the ideal gas law formula.
Explanation:
Gay-Lussac's law states that:
"For a constant mass of an ideal gas kept at constant volume, the pressure of the gas is directly proportional to its absolute temperature"
Mathematically, it can be written as:
where
p1 is the initial pressure
T1 is the initial temperature (in Kelvin)
p2 is the final pressure
T2 is the final temperature (in Kelvin)
Therefore, in order to solve for one of the 4 variables, the following steps must be adopted:
A. List your knowns and unknowns.
B. Convert temperature to kelvin.
D. Solve for the unknown.
While the following step is not needed:
C. Plug the unknowns into the ideal gas law formula.
Because we do not need to use the ideal gas law formula.
Answer:
<span>The molecules of a substance which must have the <u>a</u></span><u>bility to move past one another</u> are said to be flexible.
Explanation:
Those substances are said to be flexible which can be bent without breaking. There are many substances which are hard in nature but still can be bent. The hardness of such materials is due to strong interactions between the molecules and the flexibility comes due to their amorphous backbone. Therefore, greater the crystalline level of macromolecules lesser is the flexibility and greater the amorphous character greater is the flexibility and vice versa. Also, the flexibility of polymers is increased by adding plastisizers in it. Plastisizers make the hard polymers flexible by breaking the crosslinkers and enabling the macromolecules to move past one another.
