A gas in a piston starts out with a volume of 156 mL, a temperature of 28.1° C, and a pressure of 1.12 atm. If it ends with a volume of 312 mL and a temperature of 87.2° C, what is the new pressure?

0.67atm is the new pressure of the gas

Explanation:

To find one condition of a gas when pressure, volume and absolute temperature change we must use combined gas law:

Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.

Replacing:

P₁ = 1.12atm

V₁ = 156mL

T₁ = 28.1°C + 273.15K = 301.25K

P₂ = ?

V₂ = 312mL

T₂ = 87.2°C + 273.15 = 360.35K

1.12atm*156mL / 301.25K = P₂*312mL / 360.35K

P₂ = 0.67atm is the new pressure of the gas

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.

so what is the problem with your lab report and whats the subject of the lab report? i will you
