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.
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
State A = oxygen; State B = juice
State A = air; State B = neon
Incorrect State B:
Block of wood - solid
Neon - gas
Given:
The table of values of a linear relationship.
x y
-1 -1
0 1
1 3
2 5
To find:
The equation for the given table of values.
Solution:
If a linear function passes through the two points, then the equation of the linear relationship is
Consider any two point from the given table. Let the two points are (-1,-1) and (0,1). So, the equation of the linear relationship is
Using distributive property, we get
Subtracting 1 from both sides, we get
Therefore, the required equation is . Hence, the correct option is D.
