Answer:
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
