Question

Two states of matter are described below. State A: Changes shape and volume State B: Changes shape but not volume Which combination of the state and a substance in that state is correct?

Answer 1

Answer:

State A = oxygen; State B = juice

Option 3

Step-by-step explanation:

Given:

State A: Changes shape and volume

State B: Changes shape but not volume

Multiple Choice options:

State A = juice; State B = block of wood

State A = hydrogen; State B = block of wood

State A = oxygen; State B = juice

State A = air; State B = neon

The three states of matter are

Solid - Does not change shape or volume (like ice)

Liquid - Changes shape but not volume (like water)

Gas - Changes shape and volume (like water vapour in air)

State A must be a gas.

State B must be a liquid.

Eliminate the choice where state A is not a gas.

$X$State A = juice; State B = block of wood

    Juice is a liquid, like water.

State A = hydrogen; State B = block of wood

State A = oxygen; State B = juice

State A = air; State B = neon

Find the choice where state B is a liquid.

State A = hydrogen; State B = block of wood

$Correct$ State A = oxygen; State B = juice

State A = air; State B = neon

Incorrect State B:

Block of wood - solid

Neon - gas
