Term 4- Real and Ideal Gases

Question 1

REAL gases ________ space

Answer 1

Real gases TAKE UP space

Question 2

IDEAL gases _______ space

Answer 2

Ideal Gases DO NOT TAKE UP space

Question 3

Real gases behave more ideally at _____ temperatures and ______ pressures

Answer 3

Real Gases behave more ideally at HIGH Temperatures and LOW pressures

Question 4

Why do real gases behave more ideally at HIGH temperatures

Answer 4

High Temperature = more movement = weaker intermolecular forces = more ideal

Question 5

Why do real gases behave more ideally at LOW pressures?

Answer 5

The particles are so widely spread out that their own volume is extremely small fraction of the total volume of the gas.

Question 6

At Low temperatures gas molecules move more ______ and _______

Answer 6

At Low temperatures gas molecules move more SLOWLY and LIQUIDIFY

Question 7

Real Gases move further away from ideal at ______ Pressures, because there is a ________ volume so the particles are _______ together and the intermolecular forces become ________.

Answer 7

Real Gases move further away from ideal at HIGH Pressures, because there is a SMALLER volume so the particles are CLOSER together and the intermolecular forces become STRONGER.
