I'm confused on this matter, and can't seem to find a clear explanation online or in my book. 3.00m^3 of gas at stp is at 0 degrees C, but does that mean the pressure is 1atm? Thanks for any help.
STP stands for Standard Temperature and Pressure.
The standard temperature for STP is 0°C or 273.15 K, and the standard pressure is 1 atmosphere (atm).
The pressure at STP is considered to be 1 atm because it is the average atmospheric pressure at sea level on Earth. It is also the pressure needed to support a column of mercury 760 mm high in a barometer at sea level.
No, the pressure at STP refers to the pressure of a gas in its standard state, which is at a specific temperature and pressure. The pressure in a closed container can vary depending on the volume and amount of gas present.
The units for pressure at STP are typically measured in atmospheres (atm), but can also be expressed in other units such as kilopascals (kPa) or millimeters of mercury (mmHg).
