Temperature is directly proportional to the average kinetic energy of the molecules.
KE = 3/2 kT ...... where KE is the average kinetic energy of a molecule and k is Boltzmann's constant (1.381x10^-23 J/K).
KE = 3/2 RT ...... where KE is the average kinetic energy for a mole of molecules and R is the gas constant (8.314 J/molK).
Therefore, as KE decreases, T decreases and it gets cooler.
It gets cooler...as metal gains energy it becomes hotter and melts...
**The correct answer is C
Omitted question:I think you mean Gas A and D each exert 120 mm Hg, if Gas D has a different value , just lug it into he equation as shown below and solve.
Answer:Gas C= 670mmHg
Explanation:
According to Dalton law of partial pressure
The total pressure of a mixture of gases is the sum of the pressures of each gas and can be illustrated as
Pressure total=P1+P2+… +Pn.
Total Pressure = Gas A + Gas B + Gas C + Gas D + Gas...
Now we have
Total Pressure = 120 mm Hg + 50mm Hg + Gas C + 120 mm Hg
960mmHg = 120 mm Hg + 50mm Hg + Gas C + 120 mm Hg
960mmHg =290mmHg +Gas C
Gas C =960mmHg -290mmHg
Gas C= 670mmHg
