# Standard temperature and pressure conditions...?

What are standard temperature and pressure conditions for gases?

A) 0 C and 0 torr

B) 0 K and 760 torr

C) -273 C and 1 atm

D) 0 C and 760 torr

I think it's C, but i'm not too sure. Ideas?

Ally,

It is d for IUPAC ( International Union of Pure and Applied Chemistry and the National Institute of Standards and Technology).

0°C is 273.15°K, and 760 torr is 1 atmosphere. See citation given below!

Hope that helped!

standard temperature and pressure (STP) is 0 °C and 1 atm.

1 atom = 760 torr

0 °C = -273K

therefore the answer is D) 0 C and 760 torr

-273 C is 0 K, which is not a very standard temperature. no pressure is also not a very standard pressure. by process of elimination, it must be D. I actually didn't know that 0 C was the standard temp; i thought it was 25 C. You learn something every day!

D

It can also be written as 273.15 K and 1 atm

I think that is why you may have been confused about C
