Atank holding 7.80 l of gas is at a pressure of 9.80 atm. if the temperature and number of gas particles do not change, what is the new pressure at a volume of 5.3 l?
*show work*

a. 14.4 atm
b. 51.9 atm
c. 4.22 atm
d. 0.0693 atm

14.42 atm.

Explanation:

We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant.

T is the temperature of the gas in K.

P₁V₁ = P₂V₂

P₁ = 9.8 atm, V₁ = 7.80 L.

P₂ = ??? atm, V₂ = 5.30 L.

∴ P₂ = P₁V₁/V₂ = (9.8 atm)(7.80 L)/(5.30 L) = 14.42 atm.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
