I am currently enrolled in AP Chemistry and I want to make sure I am completing this assignment correctly. Any help is greatly appreciated and will leave a positive review! 1) Identify the type(s) of motion that individual molecules can undergo in a molecular solid. 2) When the temperature of a solid copper pipe increase, does the motion of the free electrons increase, decrease, or remain the same? 3) Draw particulate representations of a molecular liquid at a low temperature and a high temperature. Use arrows to represent velocity vectors. 4) Draw particulate representations of molecular gas at a low temperature and a high temperature. Use arrows to represent velocity vectors. 5) Draw a particulate representation of a 1.0 L sample of molecular gas in a cylinder. Draw a second particulate representation of the same sample of gas after it has been compressed to 0.5 liters. Assume that the temperature remains the same. Use arrows to represent velocity vectors. 6) Draw particulate representations that show the differences between a solid, liquid, and gas. Particle motion, intermolecular forces, and overall volume must be highlighted in the representations.

In a molecular solid, individual molecules can undergo various types of motion, including translational motion (movement from one point to another), rotational motion (spinning around a fixed axis), and vibrational motion (oscillating or shaking about a fixed position).

When the temperature of a solid copper pipe increases, the motion of the free electrons within the copper atoms will also increase. This is because an increase in temperature corresponds to an increase in the kinetic energy of the particles in a substance, which leads to an increase in their motion.

In a molecular liquid at a low temperature, the individual molecules will be moving relatively slowly, with relatively low velocities. The arrows representing the velocity vectors of the molecules will be relatively small and widely spaced.

In a molecular liquid at a high temperature, the molecules will be moving more quickly, with higher velocities. The arrows representing the velocity vectors of the molecules will be larger and more closely spaced.

In a molecular gas at a low temperature, the individual molecules will be moving relatively slowly, with relatively low velocities. The arrows representing the velocity vectors of the molecules will be relatively small and widely spaced.

In a molecular gas at a high temperature, the molecules will be moving more quickly, with higher velocities. The arrows representing the velocity vectors of the molecules will be larger and more closely spaced.

In a particulate representation of a 1.0 L sample of molecular gas, the individual molecules will be spaced relatively far apart from each other, with relatively low velocities. The arrows representing the velocity vectors of the molecules will be relatively small and widely spaced.

In a particulate representation of the same sample of gas after it has been compressed to 0.5 liters, the molecules will be spaced much closer together, with higher velocities. The arrows representing the velocity vectors of the molecules will be larger and more closely spaced.

In a particulate representation of a solid, the individual particles will be closely packed together in a regular, ordered arrangement. The particles will be vibrating in place, with little overall movement or change in position. In a particulate representation of a liquid, the particles will be more loosely packed together, with more freedom of movement.

The particles will be moving and flowing past each other, with relatively low velocities. In a particulate representation of a gas, the particles will be spaced far apart from each other, with a large amount of empty space between them. The particles will be moving quickly and randomly in all directions, with relatively high velocities.
