Volume and Pressure Table

APPH12-G8E9H8

A group of students study the an ideal gas as it changes pressure through compression. The following data table shows the gradual values of pressure and volume at ten-second intervals. The pressure data have an uncertainty of $\pm 0.01\text{ atm}$. The volume data have uncertainty of $\pm 0.05\text{ ml}$.

Time (s) Volume (mL) Pressure (atm)
0 12.2 2.04
10 15.1 1.65
20 19.3 1.29
30 24.3 1.01
40 31.0 0.80

What type of thermodynamic process is shown by these data?

A

Isothermal.

B

Isobaric.

C

Isometric (isochoric).

D

Adiabatic.
