Which of the following statements is true for real gases?

choose all that apply.
a. the volume occupied by the molecules can cause an increase in pressure compared to the ideal gas.
b. the volume occupied by the molecules can cause a decrease in pressure compared to the ideal gas.
c. as molecules increase in size, deviations from ideal behavior become more apparent at relatively low pressures.
d. as attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively low temperatures.

A. The volume occupied by the molecules can cause an increase in pressure compared to the ideal gas.

D. As attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively low temperatures.

Explanation:

as we know by real gas equation

while ideal gas equation is given as

so from above formula we can say that net pressure is increased in real gas

Also we know that all real gas will close to behave like ideal gas when the pressure of the real gas is low and temperature of the gas is high

So above are the correct observations

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y

false

hope this : d
