Five moles of an ideal gas is initially at pressure P; and volume V.. The gas is taken through a cycle as shown in Figure 3. The initial temperature of the gas is T; = 20° C. 3P; a) Calculate the net work done on the gas for one cycle. Provide a numerical answer in joules. P; A b) Calculate the net energy transferred by heat. Explain your answer. V; 3V; Figure 3

Directions: Solve the following problems. Use g = 9.80 m/s? and assume all numbers are accurate to 3 significant figures unless otherwise indicated. 1. A cylinder that has a 41.0-cm radius and is 50.0 cm deep is filled with air at 29.5°C and 1.00 atm shown in figure (a). A 21.0-kg piston is now lowered into the cylinder, compressing the air trapped inside as it takes equilibrium height hi as shown in figure (b). Finally, a 21.5-kg dog stands on the piston, further compressing the air, which remains at 29.5°C as shown in figure (c). What is the value Ah? Ah 50.0 cm h;

I need help with A and B for this problem. I want to see the detailed steps.

Part A Ideal-gas processes are often shown on a pV diagram that graphs pressure versus volume. (Figure 1) is the pV diagram for 2.0 mol of a monatomic gas that undergo a process taking them from initial state i to final state f What is the change in temperature? Express your answer in kelvins. Figure 1 of 1 p (kPa) AT = K 200 f Submit Request Answer 100 Part B 0- 0. V (L) 150 What is the change in entropy? 50 100 Express your answer in joules per kelvin.

Suppose a monatomic ideal gas is changed from state A to state D by one of the processes shown on the PV diagram. 1. The gas follows the constant-temperature path AC followed by the constant-pressure path CD. What is the total work done on the gas ? What is the total change in internal energy of the gas during the entire process?  What is the total heat flow into the gas?
