Answer:

Explanation:
Hello,
In this case, for the given constant amount and pressure of the, we apply the Charles' law which allows us to understand the volume-pressure behavior as a directly proportional relationship:

Thus, since we need to compute the volume after the temperature increase (which must be expressed in absolute Kelvins), we obtain V2 as:

Best regards.
Answer:
The answer is:
c) Is conducted below the recrystallisation temperature
Explanation:
In cold working the metal goes through a process of plastic deformation that is conducted below its recrystallization point (which its usually at room temperature), this in order to change permanently the makeup of its crystals. The temperature at which the process happens is low enough so that atoms cannot rearrange themselves.
The resulting metal is more resistant to deformation, and has an increased hardness and tensile strength.

Answer:
4
Explanation:
Since there are 3 carbons on the left side, make the coefficient of CO2 equal to 3.
Also, since there are 8 hydrogen on the left side, make the coefficient of H2O equal to 4.
This means there are 3(2)+4=10 oxygen atoms on the right, making the coefficient of O2 equal to 5.
