Use Boyle's, Charles's, or Gay-Lussac's law to calculate the missing value in each of the following.
(a) V1 = 2.0 L, P1 = 0.62 atm, V2 = 1.0 L, P2 = ?
atm

(b) V1 = 230 mL, T1 = ?, V2 = 400. mL, T2 = 298 K
K

(c) V1 = 0.55 L, P1 = 740 mm Hg, V2 = 0.84 L, P2 = ?
mm Hg Use Boyle's, Charles's, or Gay-Lussac's law to calculate the missing value in each of the following.

mm Hg

The missing value is found using the Boyle's Law and P2= 1.24 atm

The missing value is found using the Charles 's Law and T1= 171.35

Explanation:

Given data

1. Volume and pressure is given

Based on the data, the volume and pressure is given it requires the  Boyle's Law

Boyle's Law:

P1 V1 = P2V2

Given data

V1 = 2.0 L, P1 = 0.62 atm, V2 = 1.0 L, P2 = ?

(0.62 atm)(2.0L)= P2 (1.OL)

Dividing both the sides by 1.0L

we get P2= 1.24 atm

The missing value is found using the Boyle's Law and P2= 1.24 atm

2. A volume and temperature is given:

Charles Law:

V1 / T1  = V2 /T2

Given data

V1 = 230 mL, T1 = ?, V2 = 400. mL, T2 = 298 K

230 ml/ T1= 400 ml/ 298 K

T1 × 400 ml = 68450 ml × K

T1= 171.35

The missing value is found using the Charles 's Law and T1= 171.35

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
