Two states of matter are described below. state x: particles are charged and move freely state y: particles are fixed in a lattice which combination of the state and a substance in that state is correct? state x = neon; state y = milk state x = neon; state y = crayon state x = oxygen; state y = water state x = milk; state y = concrete block

Option (b) is the correct answer.

Explanation:

Plasma is defined as the hot ionized gas that consists of positively charged ions and negatively charged electrons.

Since, it is a hot gas therefore, its particles move much more rapidly from one place to another.

For example, neon is a plasma.

Whereas in solid substances only, particles are arranged in a fixed lattice because in solid state they are held together by strong forces of interaction. As a result, particles are not able to move from their position.

For example, crayon is a solid substance hence, it has a fixed lattice.

Thus, we can conclude that State X = neon; State Y = crayon.

change tension

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
