Answer:
Systems move from ordered behavior to more random behavior.
Explanation:
Entropy refers to the degree of disorderliness in a system. The second law of thermodynamics can be restated in terms of entropy as follows; “any spontaneous process in any isolated system always results in an increase in the entropy of that system.''(science direct)
According to this law, systems tend towards a more disorderly behaviour (increase in entropy) hence the answer given above.
chegg 2. What pattern did you observe measuring cell voltages with a silver electrode versus with a platinum/H2 electrode There is a difference of -0.786 V in silver
<h3>What is cell voltages ?</h3>
The difference in electric potential between two points, also known as voltage, electric potential difference, electric pressure, or electric tension, is what determines how much labor is required to move a test charge between the two sites in a static electric field. Volt is the name of the derived unit for voltage (potential difference) in the International System of Units. Joules per coulomb, or 1 volt equals 1 joule (of work) for 1 coulomb, is how work per unit charge is stated in SI units (of charge). The quantum Hall and Josephson effect was first employed in the 1990s, and most recently (in 2019), fundamental physical constants have been added for the definition of all SI units and derived units. Power and current were used in the previous SI definition for volt.

Answer:
There is a temperature of 111 K required.
Explanation:
Step 1: Data given
Volume of hydrogen gas = 6.34 L
Pressure = 1.52 atm at 298 K
The volume of the gas at a pressure of 0.720 atm is 4.98 L
Step 2:
(P1*V1)/T1 = (P2*V2)/T2
⇒ with P1 = the pressure of the hydrogen gas = 1.52 atm
⇒ with V1 = the volume of the hydrogen gas = 6.34 L
⇒ with T1 = the temperature of the hydrogen gas = 298 K
⇒ with P2 = the changed pressure of the gas = 0.720 atm
⇒ with V2 = the changed volume of the gas = 4.98 L
⇒ with T2= the temperature of the gas at 0.720 atm and 4.98L
(1.52*6.34)/298 = (0.720*4.98)/T2
0.0323 = 3.5856/T2
T2 = 110.88 K ≈111K
There is a temperature of 111 K required.
