Why do you use the first and last data points and not consecutive data points when finding a value based on info from a chart

Error gets magnified when you use consecutive data points.

The margin of error is reduced with the greater range. The first and last points represent a complete set of data.

What are the different values for pressure

1 atm= 14.7 psi= 760 torr= 760 mm Hg= 101300 Pa= 101.3 kPa

What are the different values for pressure

1 ml= 1 c^3, 1000 ml= IL

Is this a direct or indirect relationship

They must be constant

They are indirect

What kind of relationship are charles and gay-lussac’s law

Direct

In Graham’s law, make gas 1 the ____ gas

Lighter

In Graham’s law, always remember that gases can be _______

Diatomic

What is Henry’s law

The amount of gas that will dissolve in a liquid at a given temperature varies directly with the pressure above the liquid

Why do divers take precautions with solubility of gasses and temperature

As the temperature increases, the solubility of a gas decreases

So, they avoid taking hot showers so no gaseous bubbles form in the bloodstream inside the body

If a temperature increases by 15 Celsius, do you change the T or leave it C

Leave it

273 K, 1 atm, etc

Actual pressure=_________+_________

Gauge pressure, atmospheric pressure
