Answer:
-149.0K
Explanation:
Charles's law states that the volume of a gas is directly proportional to the absolute temperature under constant pressure.
The equation is:
V1/T1 = V2/T2
<em>Where V1 is initial volume = 6.00L</em>
<em>T1 is absolute initial temperature = 25.0°C + 273 = 298K</em>
<em>V2 is final volume = 2.50L</em>
<em>T2 is our incognite</em>
<em />
Replacing:
6.00L/298K = 2.50L/T2
T2 = 2.50L * 298K / 6.00L
T2 = 124.17K
The temperature is 124.17K - 273.15K =
<h3>-149.0K</h3>

Answer:
38503.5N
Explanation:
Data obtained from the question include:
P (pressure) = 5.00 atm
Now, we need to convert 5atm to a number in N/m2 in order to obtain the desired result of force in Newton (N). This is illustrated below:
1 atm = 101325N/m2
5 atm = 5 x 101325 = 506625N/m^2
A (area of piston) = 0.0760 m^2
Pressure is force per unit area. Mathematically it is written as
P = F/A
F = P x A
F = 506625 x 0.0760
F = 38503.5N
Therefore, the force exerted on the piston is 38503.5N

Explanation:
Anabolic pathways are those that require energy to synthesize larger molecules. Catabolic pathways are those that generate energy by breaking down larger molecules. Both types of pathways are required for maintaining the cell's energy balance.
