When a gas is perfect, or ideal, what properties can be related in an equation?
a.
density, velocity, temperature, and pressure
b.
density, enthalpy, temperature, and pressure
c.
mass, velocity, temperature, and pressure
d.
mass, velocity, temperature, and enthalpy
e.
density, temperature, and pressure

E.  Density, temperature, and pressure

Explanation:

According to the ideal gas equation ,

P V = n R T

n = number of moles

T = temperature .

R = universal gas constant

P = pressure

V = volume

The formula for density is given by , the mass divided by the volume .

Since , both the equation have , volume in common , hence , both the equations are linked by density .

And the temperature and the pressure are also present in the equation , which can relate to the ideal gas equation .

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.
