Problem: Six moles of a monatomic ideal gas undergo the process shown in the figure. State 1 has pressure p1 = 4.00 x 105 Pa and volume V1 = 2.00 x 10-3 m3. State 2 has pressure p2 = 3.00 x 105 Pa and volume V2 = 6.00 x 10-3 m3.  a) In this process, what is ΔU, the change in the internal energy of the gas? b) What is the heat flow Q for this process?  c) Does heat flow into the gas or out of the gas?      

🤓 Based on our data, we think this question is relevant for Professor Lyuksyutov's class at TAMU.

Problem Details

Six moles of a monatomic ideal gas undergo the process shown in the figure. State 1 has pressure p= 4.00 x 105 Pa and volume V1 = 2.00 x 10-3 m3. State 2 has pressure p= 3.00 x 105 Pa and volume V2 = 6.00 x 10-3 m3

a) In this process, what is ΔU, the change in the internal energy of the gas?

b) What is the heat flow Q for this process? 

c) Does heat flow into the gas or out of the gas?
