STP (standard gas temperature and pressure) for ideal gases obeying PV=nRT:
n = number of moles
R = universal gas constant = 8.3145 J/mol K
N = number of molecules
k = Boltzmann constant = 1.38066 x 10-23 J/K = 8.617385 x 10-5 eV/K
k = R/NA
NA = Avogadro's number = 6.0221 x 1023 /mol

Physical state of substances properties and behavior at room temperature and standard atmospheric pressure?
The physical state of a substance in relation to its properties and behavior at room temperature and standard atmospheric pressure will simply be the lowest energy state for the substance. This is the state that the substance can't help but go back to, unless energy is put in to do otherwise.
What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
What temperature is it impossible to liquify a substance no matter the pressure?
Any temperature below 0 Kelvin or -273.15 Celsius is impossible. +++ ... Because it indicates the body in question contains no heat energy.
What substance present in your body balances the atmospheric pressure acting on us?
our blood
What is the relationship between presssure and the boiling point of Liquids?
Boiling point is nothing but point at which liquid starts changing from liquid state to vapor state. liquid changes to vapor when vapor pressure equal to surrounding pressure. so if surrounding pressure is less boiling point is less and boiling point is high if surrounding pressure is high this point is on view of pressure
Choose the best definition of STP?
a term that indicates a combined measurement of standard atmospheric pressure and room temperature. A+

What is the temperature of liquid nitrogen at atmospheric pressure is it always -196C or can it be colder?
Well, let's think about it. What is the temperature of liquid waterat atmospheric pressure ? Is it always 99°C or can it be colder ?Seems like the temperature of any liquid substance can be anywherebetween its boiling point and its freezing point.
What substance present in your body balances the atmospheric pressure actin on us?
what substance present in your body balances the atmospheric pressure action on us
What is the normal melting point?
It is the temperature at which a substance, under normal atmospheric pressure changes from the solid phase to the liquid phase.
What are the type of pressure change indicates stormy weather?
A drop in atmospheric pressure.
What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
What is the relationship of speed of sound to the atmospheric pressure?
There is a relationsship of speed of sound to the temperature but not to the atmospheric pressure.
What does rising atmospheric pressure usually indicates?
a high pressure system is moving into an area
What temperature is it impossible to liquify a substance no matter the pressure?
Any temperature below 0 Kelvin or -273.15 Celsius is impossible. +++ ... Because it indicates the body in question contains no heat energy.
What happens at a substance's boiling point?
Its vapor pressure equals atmospheric pressure.
What does it mean when the atmospheric pressure at place fall suddenly?
A drop in pressure usually indicates bad weather.
