Which of the following properties is shared by gases and plasma?
their particles are far apart.
they have a definite shape.
they consist of uncharged particles.
their particles vibrate in fixed positions.

Their Particles are far apart.

Explanation:

Plasma : It is the hot ionised - gas. It consists of equal number of positive charge particles and negative charged particles .

Gas : It consists of mixture of neutral atoms and molecules(Gaseous).

In both plasma and gases the particles can move freely.

The correct answer is A. Their particles are far apart

Explanation:

Gas and plasma are two different states of matter; however, these two states share certain features. This includes the fact they do not have a defined shape or volume and the particles in both gases and plasma are fart apart, which allow them to move more than in liquids or in solids and explain why neither plasma nor gases have a define shape or volume. Besides this, in plasma particles are mainly charged and this causes them to move more frenetically than in gases. According to this, the property that is shared by gases and plasma is "their particles are far apart".

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
