  • Ava said she could tell what phase a substance is in just by looking at it. How can she do this?
    She could tell by the amount of space the substance takes up
    She could tell by the way the molecules move around each other
    She could look at the temperature
    She could look at the different molecules inside

  • Liquid oxygen and liquid helium are very different, but they have one thing in common. That one thing is...
    they are moving and flowing around each other
    they are always changing, but they move around
    they are locked together and moving in place
    they are moving around freely and flying apart

  • A solid piece of butter is placed over heat on the stove. After some time, the butter becomes a liquid. Why?
    the butter molecules were destroyed
    the butter molecules changed into water
    the butter molecules became more loosely connected
    the butter molecules got smaller

  • Lee has a substance in a closed container. The molecules move in place. What will happen if energy is transferred in?
    the molecules will move faster and become a liquid
    the molecules will move faster and become a gas
    the molecules will move slower and become a liquid
    the molecules will move slower and become a solid

  • The snowcone below sat outside for 30 minutes and then melted. What do we know about the snowcone BEFORE it melted?
    It was a solid that had molecules that flowed around each other
    It was a liquid that had molecules that flowed around each other
    It was a liquid that had molecules that moved in place
    It was a solid that had molecules that moved in place

  • The snowcone below sat outside for 30 minutes and then melted. What do we know about the snowcone AFTER it melted?
    energy was transferred out of the snowcone
    energy was transferred into the snowcone

  • Zoe's barn door will not close when the temp gets hot outside, but in colder months it closes easily. Why? CHOOSE 2
    When thermal energy transferred in, the door expanded
    When thermal energy transferred in, the door contracted
    When thermal energy transferred in, the molecules gained kinetic energy
    When thermal energy transferred in, the molecules lost kinetic energy

  • This model shows a solid ice cube. How should we fix this model to better represent a solid and why?
    Shorten the arrows because there is less kinetic energy in a solid
    Remove all of the arrows since solids do not have any kinetic energy
    Make the arrows longer because solids have more kinetic energy
    The model should not be changed
