273 K (0° Celsius) and 1 ATM pressure
Water boils at 212o F at standard pressure.
LESS
At room temperature and pressure it is in liquid state. Its melting point is 280 K under standard pressure.
Because that is the definition of 1 atmosphere at standard temperature.
STP; 101.3Kpa & 273K (0*C)SATP; 100Kpa, 298K (25*C)
25± C, 1 ATM
International (IUPAC) values are: 0 oC and 10e5 Pa.Only in USA the values are 20 oC and 1 atm.Sometimes other values are used.
That is the element potassium at STANDARD TEMPERATURE AND PRESSURE. Standard temperature is 273 K and standard pressure is 1 atm.
Lithium is a solid metal at standard temperature and pressure.
there is no difference
No: hydrogen sulfide is a gas at standard room temperature and pressure
For chemistry, after IUPAC rules the standard temperature is 0 oC and the standard pressure is1 bar.
At STP(Standard Temperature and pressure), the temperature is zero degrees Celsius(273 Kelvin) and the pressure is 1 atmosphere. At RTP(Room temperature and pressure), the temperature is 25 degrees Celsius(298 Kelvin) and the pressure is 1 atmosphere.
If the water is pure, and the temperature and pressure are both at standard values,then the mass of one milliliter of water is 1 gram.
STP means standard temperature and pressure and VTP means volume temperature and pressure oh and btw standard temperature and pressure is 0 degrees Celsius and 1 atmosphere
standard temperature and pressure
There are different values of NTP, depending on the standard that you use. Two examples are IUPAC: 0 C and 100 kPa, and NIST: 20 C and 101.325 kPa.
