What is the result when energy is transferred to a substance?
What is the result when energy is transferred to a substance?
- The atoms/molecules do not change speed.
- The atoms/molecules lose energy and move slower.
- The atoms/molecules expand and their volume decreases.
- The atoms/molecules gain energy and move faster. (correct)
What happens to the volume of a substance when it is warmed?
What happens to the volume of a substance when it is warmed?
- The volume remains the same as the atoms/molecules do not change size.
- The volume changes randomly and unpredictably.
- The volume increases as the atoms/molecules spread further apart. (correct)
- The volume decreases as the atoms/molecules get closer together.
What is the relationship between temperature and the speed of atoms/molecules?
What is the relationship between temperature and the speed of atoms/molecules?
- The faster the atoms/molecules move, the higher the temperature. (correct)
- Temperature is a measure of the total energy of the atoms/molecules.
- The faster the atoms/molecules move, the lower the temperature.
- Temperature and speed of atoms/molecules are unrelated.
