Two containers, one at 305 K and the other at 295 K, are placed in contact with each other. a. 1 J of heat flows from the hot container to the cold container. Find the change in entropy of the hot container and the cold container, and of the whole system (hot + cold container together). Does this process violate the second law of thermodynamics? b. 1 J of heat flows from the cold container to the hot container. Find...

Two containers of the same gas each holding the same amount of mass, initially at temperature T1 and T2 are brought into thermal equilibrium Assuming no heat loss to the atmosphere and constant container volumes calculate (neglect the mass of the containers): 1) The final temperature of the gas in each container 2) The change of internal energy 3) The change of entropy For this process- if: A) The containers are placed in thermal contact. B) A reversible cycle works...

Difference in final temperatures? Please show all steps
Two containers (call them A and B) with the same initial volume, V 31 L, hold the same amount of monatomic ideal gas, say helium, at the same initial temperature T = 301 K and the same initial pressure Pi 1 atm. Container A holds the gas at a constant volume and Container B holds the gas at a constant pressure If you add Q 5389 J of heat to both containers,...

One container holds 0.10 kg of water at 75 ∘C and is warmed to 95 ∘C by heating from contact with the other container. The other container, also holding 0.10 kg of water, cools from 25 ∘C to 5.0 ∘C. Specific heat of water is 4180 J/kg⋅∘C. Estimate the total change in entropy of two containers of water using the actual temperatures to determine the heat transferred to each container and the average temperatures to determine the change in entropy....

One container holds 0.10 kg of water at 80 ∘C and is warmed to 100 ∘C by heating from contact with the other container. The other container, also holding 0.10 kg of water, cools from 35 ∘C to 15 ∘C. Specific heat of water is 4180 J/kg⋅∘C. Estimate the total change in entropy of two containers of water using the actual temperatures to determine the heat transferred to each container and the average temperatures to determine the change in entropy....

Two plates with the same area A are placed in contact with each
other as shown in the figure. The plates have thickness x1 and x2
and thermal conductivity k1 and k2. Heat is passed from left to
right through the plates from a high temperature range T1 to a low
temperature range T2. The temperature of the plates' contact
surface is Tm, on the flat side to the far left T1 and the flat
side to the far right...

Two copper blocks, each of mass 1.25 kg, one at 54°C and the other at 0eC, are placed in contact in an isolated container (so no heat can escape) and allowed to come to equilibrium. Calculate the final temperature of the two blocks (in K), the entropy change of each (in נ-K 1), and AStot (in נ-K 1). The specific heat capacity of copper is 0.3853-K 1-g 1 and may be assumed constant over the temperature range involved final temperature...
