1 answer

Let's evaluate each statement to determine which ones are true:

  1. The molecules in hot tea have more motion energy than the molecules in my ice tea.
    This statement is true. Hot tea has a higher temperature, which means its molecules have more kinetic energy compared to the molecules in iced tea.

  2. Liquid water can freeze into ice by absorbing heat energy.
    This statement is false. Liquid water freezes into ice by releasing heat energy, not by absorbing it.

  3. Absorbing heat energy makes molecules and atoms move more.
    This statement is true. When heat energy is absorbed, it increases the kinetic energy of the molecules and atoms, causing them to move more.

  4. Absorbing heat energy makes molecules and atoms have less motion energy.
    This statement is false. Absorbing heat energy increases the motion energy of molecules and atoms.

  5. Melted, liquid butter has more kinetic energy than when it was solid in the refrigerator.
    This statement is true. When butter is melted, its molecules move more freely and have higher kinetic energy compared to when it is solid.

Based on this evaluation, the true statements are:

  • The molecules in hot tea have more motion energy than the molecules in my ice tea.
  • Absorbing heat energy makes molecules and atoms move more.
  • Melted, liquid butter has more kinetic energy than when it was solid in the refrigerator.
