Air contained within a piston-cylinder assembly undergoes three processes in series: A) Process 1-2: compression at constant pre

ssure from P1=10lbf/in2, V1=4ft3 to state 2. B) Process 2-3:Consant volume heating to state 3, where P3=50lbf/in2. C) Process 3-1: Expansion to the initial state, during which the pressure-volume relationship is PV=constant. Sketch the process in series on P-V coordinates. Evaluate the (A) volume at state 2, in ft3, (B) work for each process, in Btu

What are the intercepts of y = x + 5 (Remember that intercepts mean both x-intercept & y-intercept.) a) (5, 0) & ( 0, 5)
DaniilM [7]

Greetings from Brasil...

We have to remember 2 details:

→ When X = 0, the function intersects the Y axis

→ When Y = 0, the function intersects the X axis

So

1: X = 0

Y = X + 5

Y = 0 + 5

Y = 5

X = 0 and Y = 5 ⇔ (0; 5)

2: Y = 0

Y = X + 5

0 = X + 5

X = - 5

Y = 0 and X = - 5 ⇔ (- 5; 0)

Then the point at which the graph intersects the X and Y axis will be

(0; 5) and (- 5; 0)
