Answer: When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel. Furthermore, when a liquid is poured from one vessel to another, it retains its volume (as long as there is no vaporization or change in temperature) but not its shape.
Explanation: A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume. Plasma is similar to a gas in that its particles are very far apart, but a gas is electrically neutral and plasma has a charge.
Given what we know, as with all substances, the particles in the bowl of hot soup will slow down as they cool after being poured.
<h3>Why do particles slow when cooled?</h3>
- This has to do with energy.
- The soup particles are excited by heat energy.
- As the soup is poured, its heat energy radiates and it loses energy.
- Decreased energy causes the particles to slow down.
Therefore, the motion of the particles of the soup decrease or slows down as the soup cools due to the loss of energy they are experiencing. The soup radiates heat energy into the room or plate, causing the particles to lose energy and slow down.

The acceleration of the wooden box is 6.17 m/s² towards the west.
<h3 /><h3>What is acceleration?</h3>
Acceleration can be defined as the rate of change of velocity.
To calculate the acceleration of the wooden box can be calculated using the formula below.
Formula:
- F₂-F₁ = ma.................. Equation 1
Where:
- F₂ = Force on the wooden box acting towards west
- F₁ = Force on the wooden box acting towards the east
- m = Mass of the wooden box.
- a = Acceleration of the wooden box
Make a the subject of the equation
- a = (F₂-F₁)/m........................ Equation 2
From the question,
Given:
- F₂ = 270.7 N
- F₁ = 85.7 N
- m = 30 kg
Substitute these values into equation 2
- a = (270.7-85.7)/30
- a = 185/30
- a = 6.17 m/s² towards the west.
Hence, The acceleration of the wooden box is 6.17 m/s² towards the west.
