A sample of NO2 in a 1550 mL metal cylinder at 70.26 kPa has its temperature changed from 480oC to -237oC while its volume is simultaneously changed by a piston to 5114 mL. What is the final pressure in kPa?

1.02KPa

Explanation:

The following were obtained from the question:

V1 = 1550mL

P1 = 70.26kPa

T1 = 480°C = 480 + 273 = 753K

T2 = -237°C = - 237 + 273 = 36K

V2 = 5114mL

P2 =?

The final pressure can obtain as follows:

P1V1/T1 = P2V2/T2

(70.26x1550)/753 = (P2x5114)/36

Cross multiply to express in linear form as shown below:

P2 x 5114 x 753 = 70.26 x 1550 x 36

Divide both side by 5114 x 753

P2 = (70.26x1550x36)/(5114x753)

P2 = 1.02KPa

Therefore, the final pressure is 1.02KPa

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
