Changes of states of matter
What is the change of state from solid to liquid
What is melting
What is diffusion
The movement of particles from an area of high concentration to low concentration

What happens to the volume of a gas when temperature increases (pressure constant)?
Volume increases.
Which state of matter keeps its own definite shape and definite volume, no matter what container you put it in?
A) Gas
B) Liquid
C) Solid
C
In the morning, you might see drops of water on the grass. This happens when water vapor (gas) in the air cools down and turns back into a liquid. What is this process called?
Condensation
If you spray perfume in one corner of a room, eventually people on the other side of the room can smell it. Why does this happen
The perfume particles bump into air molecules and spread out randomly until they fill the room.
Yes or no
Yes = -1000 no = -2000
What happens to the volume of a gas when temperature decreases?
Volume decreases.
What happens to the shape of a liquid (like water or juice) when you pour it from a round bowl into a square box?
A) It stays in the shape of the round bowl.
B) It changes to take the shape of the square box.
C) It instantly turns into a gas.
B
To make ice cream, a liquid mixture is placed in a very cold freezer until it becomes a solid. What change of state is taking place
Freezing
In which state of matter does diffusion happen the fastest
Gas
Heads or tails
Heads = +1000 Tails=-1000
Why does a hot-air balloon rise when the air inside is heated?
Heated air expands, becomes less dense than surrounding air, and rises.
Which state of matter has no fixed shape and no fixed volume, expanding completely to fill up any container or room it is released into?
A) Solid
B) Gas
C) Liquid
C) It instantly turns into a gas.
B
After a rainy day, the sun comes out and dries up a puddle on the sidewalk by turning the liquid water into a gas. What is this process called?
How does increasing the temperature affect the rate of diffusion
It speeds up diffusion because particles gain kinetic energy and move faster.
🤓 or 😎
🤓= +1000 😎= -1000
State the relationship between pressure and volume at constant temperature.
They are inversely proportional
Why can gases be easily compressed (squeezed into a smaller space), while solids cannot?
A) Gas particles are spread very far apart with lots of empty space between them.
B) Gas particles are much larger than solid particles.
C) Solids are actually made of liquid
A
When you boil water in a kettle, you see steam rising out of the spout. This fast change from a liquid to a gas throughout the liquid is known as:
A) Freezing
B) melting
C) Condensation
D) Sublimation
200 points extra if you said none
Which of the following is an example of diffusion in the human body?
A) Blood pumping through the heart.
B) Oxygen moving from the lungs into the blood.
C) A bone healing after a fracture.
D) The stomach digesting a meal.

A sealed container of gas is heated. The volume cannot change.
What happens to the pressure and why?
Pressure increases because particles move faster and collide with the container walls more frequently and with greater force.
If you could look through a super-powerful microscope at a solid object (like a wooden block), what would you see the particles doing?
A) Flying around rapidly and bouncing off each other.
B) Sliding and tumbling past one another freely.
C) Locked tightly in place and vibrating gently.
C but sadly you get half points
