Chemistry Question on States of matter
A gas deviates from ideal behaviour at a high pressure because its molecules
A
attract one another
B
show the Tyndall effect
C
have kinetic energy
D
are bound by covalent bonds
Answer
attract one another
Explanation
Solution
At high pressure, the volume is decreased appreciably, so the attractive forces become large and the molecules are crowded together. Thus, pressure correction is necessary and the gas deviates more from ideal behaviour.
