A chemist is conducting an experiment on a system. At the beginning of the experiment, the chemist wants to determine the temperature of the system. The system has a definite volume but no definite shape. Which of the following is most likely also true for the system?

• The molecules in the system have less kinetic energy than a solid.

• 1. The molecules in the system have more kinetic energy than a solid.

• 1. The molecules are held together by stronger attractive forces than a solid. 

• 1. Heat flow into the system would eventually cause it to have a definite shape.

1. A group of student classified certain things as matter or energy and came up with the following classification:

Matter: atoms, sugar, water, air 

Energy: heat, potential, kinetic, sound

Which of the following provides the best scientific explanation as to why the things classified as energy are not also classified as matter?

• 1. The things classified as matter are only used to generate energy. 

• 1. Energy makes matter move, and the things classified as energy only make matter move.

• 1. You cannot hold the things classified as energy, so that must mean they cannot be classified as matter.

• 1. All matter has mass and occupies space, and the things classified as energy do not have mass and do not take up space.
