Chapter 8: Q. 8.65 (page 281)

At 100掳Cwhich of the following diagrams (1,2,or3)represents a gas sample that exerts the:(8.1)

a. lowest pressure?

b. highest pressure?


Short Answer

Expert verified

a. The lowest pressure in the diagram (2): .

b. The highest pressure in the diagram (1): .

Step by step solution

01

Part (a) step 1: Given Information

We need to find the lowest pressure in the given diagrams.

02

Part (a) step 2: Simplify

If volume and temperature is the same the pressure is related to the number of mole of the sample. The number (2)has the lowest molecule. Therefore has the lowest pressure.


03

Part (b) step 1: Given Information

We need to find the highest pressure in the given diagrams.

04

Part (b) step 2: Simplify

If volume and temperature is the same the pressure is related to the number of mole of the sample. The number (1)has the highest molecule. Therefore has the highest pressure.
