Chemistry: Particles in Motion

What are the three states of matter?

• Solid

• Wet

• Gas

• Frozen

• Liquid

How do you make a mixture?

• By combining 2 or more substances.

• By pouring lots of one substance into a cup.

• By stirring water

Do solids have high or low kinetic energy?

• Low (the particles don't move very much)

• High (the particles move around a lot)

Which state of matter has the highest kinetic energy (the particles move around the most)?

• solid

• liquid

• gas

When you heat up a solid, liquid, or gas, what happens to the kinetic energy of the particles?

• increases

• decreases

• stays the same

Choose the vocabulary word being described: the ratio of mass and volume in a sample of matter

• mixture

• matter

• density

• kinetic energy

Choose the vocabulary word being described: energy of motion

• mixture

• matter

• density

• kinetic energy

What happens to the size of gas particles when the air is heated?

• they grow and their kinetic energy increases

• they stay the same and their kinetic energy increases

• they shrink and their kinetic energy shrinks

What will happen to the volume of a balloon filled with air if the TEMPERATURE OF THE GAS INSIDE THE BALLOON INCREASES

• grow

• shrink

• stay the same

What will happen to the volume of a balloon filled with air if the TEMPERATURE OF THE GAS INSIDE THE BALLOON DECREASES

• grow

• shrink

• stay the same
