Calculate the work associated with the expansion of a gas

Mathematics
1 answer:

Answer:

-27 kJ

Step-by-step explanation:

Given data

  • Initial volume (Vi): 46 L
  • Final volume (Vf): 64 L
  • External pressure (P): 15 atm

We can find the work (w) associated with the expansion of a gas using the following expression.

w = - P . ΔV

w = - P . (Vf - Vi)

w = - 15 atm . (64 L - 46 L)

w = -270 atm.L . (101.325 J/ 1 atm.L)

w = -2.7 × 10⁴ J

w = -27 kJ

If a set xy-axes has 20 grid units in each direction and the greatest value of the data to be placed on the horizontal axis is 1
Alborosie
Use 7 scale point.
132/20 = 6.6
to its better to use more than 6.6 scale. to make it easier use 7, so to avoid decimals

20 points<br> What is the value of p in the linear equation ?<br><br> −4<br> −2<br> 2<br> 4
Nikolay [14]

Answer:

p=-2

Step-by-step explanation:

24p+12-18p=10+2p-6  

Subtract what is to the right of the equal sign from both sides of the equation.

24p+12-18p-(10+2p-6)=0

Then pull out the like terms(factors)

Which is: 4p+8

=4(p+2)

Put that to 0 and 4=0 which is not a solution because it's a non-zero constant.

So now put  p+2=0, subtract by 2 on both sides and the 2 cancels out and on the right side you have -2

p=-2
