Problem

Standard temperature and pressure (STP), in the context of gases, refers to __________.

a. 298.15 K and 1 atm

b. 273.15 K and 1 atm

c. 298.15 K and 1 torr

d. 273.15 K and 1 pascal

e. 273.15 K and 1 torr

Solution

We have to define what STP (standard temperature and pressure) means in the context of gases.

Temperature is defined as the degree of heat present in a substance or object.

Pressure is the force exerted by gas molecules on the unit area of the container.
