Answer:
A) Having a positive slope
D) Approaching zero pressure as temperature approaches infinity
Explanation:
A fixed amount of ideal gas is kept in a container of fixed volume. The absolute pressure P, in pascals, of the gas is plotted as a function of its temperature T, in degrees Celsius. Which of the following are properties of a best fit curve to the data? Select two answers.
A) Having a positive slope
B) Passing through the origin
C) Having zero pressure at a certain negative temperature
D) Approaching zero pressure as temperature approaches infinity
solution
from the ideal gas equation
PV=nRT
P=pressure
T=absolute temperature in kelvin
V=volume
R=gas constant 8.314j/molK
n=mole= mass/molecular mass
P=nRT/V
nR/V is the constant
P=nR(Tc+273)/V
plotting the graph we will discover that as pressure increases , temperature also increases . which means it's a positive graph.
Also Approaching zero pressure as temperature approaches infinity
