Water does not boil at STP. STP stands for standard temperature and pressure. You've got to either increase the temperature or decrease the pressure.
Most likely you want to know what the boiling point of water is at standard pressure. This is complicated somewhat by the fact that STP is not as simple as it used to be and is now defined by IUPAC as 100 kPa but by NIST as 1 ATM (101.325 kPa). Using NIST standard pressure, the boiling point of water is 373.15 K; using IUPAC's value, it's 372.78 K (approximately... I couldn't find exactly 100 kPa in my vapor pressure tables, so I had to interpolate a little; that last digit may be off slightly).
Somewhat less likely is that you want to know what pressure is required to make water boil at standard temperature. Again, two competing standards; IUPAC's is 273.15 K and NIST's is 293.15 K. IUPAC's value leads to a pressure of 4.579 Torr, which is 0.610 kPa; NIST's value yields a pressure of 17.535 Torr or 2.34 kPa.
All values are straight from vapor pressure tables in the CRC Handbook of Chemistry and Physics (60th Ed.) modulo a units conversion, except for the one for IUPAC standard pressure which I had to interpolate as noted above.
1) Hydrogen GAS does not boil, simply because a gas is beyond the boiling stage.
2) STP (Standard Temperature and Pressure) is a set variable. Therefore, this question is syntactically incorrect, because you are asking: What is the boiling point of 'substance' at X°C and X psi, in which case you can't answer because of the already given temperature.

Just for two other ways that are similar to your question that can be answered are...
Q: What is the boiling point of hydrogen at SP?
A: Roughly 20K, yea really cold.
or...
Q: Does hydrogen boil at STP?
A: No...

Pure water at STP boils at 212 degrees Fahrenheit.
Dihydrogen Monoxide (H2O) is water. It boils at 100C or 212F at STP.
At STP ie (1 Atm or 101.325 kPa, 760mm Hg) The boiling point of pure water is 212 °F or 100 °C The freezing point of pure water is 32 °F or 0 °C
Boiling point is consistant with the given air pressure. At 760 mmHg air pressure (STP) then the boiling point of water is 100 oC. Water boils at 99.97 °C (211.95 °F) under standard pressure at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft).
The boiling point of freshwater is lower than the boiling point of saltwater.
Pure water at STP boils at 100 degrees Celsius, which is 373.15 Kelvin.
Pure water at STP boils at 212 degrees Fahrenheit.
Dihydrogen Monoxide (H2O) is water. It boils at 100C or 212F at STP.
Oxygen is boiling at 90.20 K (-182.95 °C) when at STP
At STP ie (1 Atm or 101.325 kPa, 760mm Hg) The boiling point of pure water is 212 °F or 100 °C The freezing point of pure water is 32 °F or 0 °C
Petroleum is a MIXTURE of organic compounds, all of which are above their melting point at STP and some of which are near their boiling point at STP. This means that at STP petroleum is a volatile liquid.
Nonpolar molecules
the unit of mass is the mass of one cubic centimeters of water at STP. - gram the unit of temperature (degrees Kelvin or Kelvins) is related to the difference between the freezing point ofd pure water and the boiling point at STP. - Celsius, reduced to absolute zero for Kelvin.
Technically speaking, boiling is when the pressure inside the system is equal to that of the surroundings. That means that you can boil water at room temperature if you have a vacuum pump. If you mean just to the heat that it starts to boil at STP, then no, it doesn't. Boiling point at STP is and always will be 100 degrees Celsius.
The Boiling Point is the point at which a substance at liquid state boils. The temperature that the liquid has to reach to be at Boiling Point (B.P) ranges, it is different for each liquid. The B.P for water is 100 degrees Celsius.
At STP Silicon boils at 3,265 °C.
Boiling point is consistant with the given air pressure. At 760 mmHg air pressure (STP) then the boiling point of water is 100 oC. Water boils at 99.97 °C (211.95 °F) under standard pressure at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft).
