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

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
