States of Matter Quiz

Which state of matter is both incompressible and fluid?

• Liquid

• Solid

• Gas

• Plasma

What is the molecular formula of ice?

• H2O

• O2

• CO2

• H2

Why is ice considered rigid?

• Because its molecules are far apart

• Because its molecules are compressible

• Because its molecules are in a fixed pattern

• Because its molecules are moving rapidly

What type of change occurs when ice melts into water?

• Biological change

• Physical change

• Nuclear change

• Chemical change

Which type of molecular movement is NOT shown in the video?

• Translation

• Rotation

• Vibration

• Diffusion

What happens to water molecules when it turns into steam?

• They form new bonds

• They break apart

• They move closer together

• They move farther apart

Why are gases compressible?

• Because their molecules are tightly packed

• Because their molecules are far apart

• Because their molecules are stationary

• Because their molecules are in a fixed pattern

What is the relationship between temperature and molecular speed?

• Temperature only affects solids

• Temperature has no effect on molecular speed

• Higher temperature increases molecular speed

• Higher temperature decreases molecular speed
