Give the temperature and pressure at STP.
A) 0°C and 1.00 atm
B) 0K and 760 torr
C) 25°C and 760 in Hg
D) 300 K and 1 torr Hg
E) 0°C and 1 mm Hg

Question

Quizplus · Accepted Answer

STP (Standard Temperature and Pressure) is defined as 0°C and 1.00 atm. Therefore, option A is the correct choice. Option B is incorrect because 0K is impossible and STP is defined in terms of Celsius temperature. Option C is incorrect because STP is defined in terms of pressure in atm, not in Hg. Option D is incorrect because the temperature is given in Kelvin, which is the same as °C at STP, but the pressure is given in torr Hg, which is not the standard unit for pressure at STP. Option E is incorrect because the pressure is given in mm Hg, which is not the standard unit for pressure at STP.
