Room Temperature And Pressure

Satp standard ambient temperature and pressure.

Room temperature and pressure.

At this temperature and ordinary pressure only two elements are liquids. When it occupies a larger volume it exerts a lower pressure assuming the amount of gas and the temperature do not change. Nist uses a temperature of 20 c 293 15 k 68 f and an absolute pressure of 1 atm 14 696 psi 101 325 kpa. Satp standard ambient temperature and pressure is a reference with temperature of 25 o c 298 15 k and pressure of 101 325 kpa.

For science it s usually considered to be either 20 c or 25 c. Room temperature is what people expect a room to heated or cooled to. Colloquially room temperature is the range of air temperatures that most people prefer for indoor settings which feel comfortable when wearing typical indoor clothing. In this context it would be expected that extremes of either pressure or temperature are not expected.

There is really no such thing as room pressure it is simply no. At these conditions the volume of 1 mol of a gas is 24 4651 liters. Room temperature is a loosely defined term that can mean anywhere from 20 c to 29 c. Satp standard ambient temperature and pressure is also used in chemistry as a reference.

Volume pressure data for an air sample at room temperature are graphed in figure 5. This standard is also called normal temperature and pressure abbreviated as ntp. Human comfort can extend beyond this range depending on humidity air circulation and other factors. The international standard metric conditions for natural gas and similar fluids are 288 15 k 15 00 c.
