BACKGROUND:
o
This table gives the values for Standard Temp. (in °C & K) & Pressure (in kPa & atm).
o
Standard Temperature and Pressure (STP) refers to normal conditions in the atmosphere. This value is important because it is used to enable comparisons/ conversions to be made between sets of data/data with different units.
•
USES:
o
REFERRED TO IN: MATTER, ENERGY, & GAS LAWS
•
Use known equivalencies at STP given on Table A to CONVERT between units of pressure! (Remember pressure values for mmHg & torr are NOT given on the ref. table.)
•
Use when doing GAS LAW PROBLEMS. If a gas is said to be at STP, use the given temperature and pressure values listed on Table A as your values for temperature & pressure in the gas law problem.
•
Ex) 1 liter of a gas at STP is compressed to 473mL and the temperature decreases to 243K. What is the new pressure of the gas in atm?
o
Many students may read this and think, there is not enough info, BUT, since the question states that the gas is at STP, your P 1 and T 1 values are 1 atm and 273K respectively. (The rest of the question is done as a typical gas law problem, using the combined gas law eq.)

New York State Science Reference Tables
The Reference Tables are an invaluable tool to the high school science student. They contain important measurements, equations, maps, and identification tables. The booklets are frequently used during classes, tests, and lab assignments. The Reference Tables are also used on the New York State Regents Exams.

Mr. Albetta is one of the good guys! . It makes sense that Evan Charles and Long John Silvers love him so much!
ReplyDeleteI agree! Albetta is a tough AP, but he's resonable and is a good guy to work for!
DeleteI agree also!

The words I would use to describe Mr. Albetta is "Highly Effective"!
