A hypothetical gas that perfectly fits all the assumptions of the kinetic molecular theory is known as

• real gas

• ideal gas

• imaginary gas

• perfect gas

According to kinetic molecular model, in gases,

• The particles are closely packed together, they occupy minimum space and are usually arranged in a regular pattern

• The particles occur in clusters with molecules slightly further apart

• The molecules are very far apart and occupy all space made available to them

• The particles vibrate about fixed positions and are held together by strong intermolecular bonds between them

Which is a quality that only gasses display

• Spread out to fill all available space

• Take the shape of their container

• Can't be compressed

• All of these

The average _______ energy of all the particles determines the temperature of the gas.

• potential

• kinetic

• chemical

• mechanical
