Phase changes intro reading comprehension

What is phase change?

• Transformation of matter from one state to another

• Change in temperature of matter

• Change in color of matter

• Change in shape of matter

Why does temperature stop increasing at certain points?

• Due to phase changes

• Due to pressure changes

• Due to chemical reactions

• Due to gravitational forces

How does adding energy to a material affect its temperature?

• Decreases the temperature

• Has no effect on the temperature

• Increases the temperature

• Changes the color of the material

Energy during a phase change goes into breaking attractive forces..

(a)  

How does the constant temperature during a phase change affect the energy involved in the process?

How does added energy affect the molecular motion in liquid water?

• Decreases molecular motion

• Has no effect on molecular motion

• Increases molecular motion

• Causes molecular motion to stop

How does energy distribution impact the temperature behavior of water molecules?

• It has no effect on the temperature behavior

• It decreases the temperature of water molecules

• It increases the temperature of water molecules

• It affects the movement and arrangement of water molecules

What effect does increased kinetic energy have on liquid and gaseous water?

• Decreases temperature

• No effect on temperature

• Increases temperature

• Causes phase change

What is the role of energy in liquid water?

• To form hydrogen bonds

• To break hydrogen bonds

• To increase the temperature

• To decrease the temperature

What happens when hydrogen bonds are broken in gaseous water?

• Molecular motion decreases

• Temperature decreases

• Molecular motion and temperature increase

• Molecular motion and temperature remain constant
