The entropy decreases in this system.

Entropy is the measure of change in disorder of the system. The entropy increases with the increase in number of possible states of a system.

Entropy of a system depends upon the temperature. Burning of gasoline produces gases at high temperature, the disorder of the system increases. Therefore, the entropy increases due to the high temperature of the gases produced

Ore is the impure form of the metal; similarly, the gold ore contains gold metal along with the impurities. Hence, due to the impurities in the ore, there is high rate of disorder inthe ore. But the disorder decreases when the gold is separated from the ore as the gold contains lesser impurities than the ore. Therefore, the entropy decreases in this system.

the Temperature of a sample of an ideal gas in a sealed 5.0 l container is raised from 27 oC to 77oC. If the initial pressure of
matrenka [14]
Answer:
              The pressure increases to 3.5 atm.

Solution:
                According to Gay-Lussac's Law, " At constant volume and mass the pressure of gas is directly proportional to the applied temperature".

For initial and final states of a gas the equation is,

                                           P₁ / T₁  =  P₂ / T₂
Solving for P₂,
                                           P₂  =  P₁ T₂ / T₁    ----- (1)

Data Given;
                   P₁  =  3 atm

                   T₁  =  27 °C + 273  =  300 K
 
                   T₂  =  77 °C + 273  =  350 K

Putting values in eq. 1,

                                           P₂  =  (3 atm × 350 K) ÷ 300 K

                                           P₂  =  3.5 atm

Which element has 1s2s2p3s3p electron configuration?
Rus_ich [418]
To answer this problem, we need to count the electrons in the given configuration. The complete configuration is 1s2 2s2 2p6 3s2 3p6. There are 2+2+6+2+6 equal to 18 electrons. We find next the element with an atomic number of 18. That element is noble gas argon.
