A student is shown a simple model of particles that make up a liquid, as shown
su
How should the model be changed to show the particles of a liquid at a higher temperature?
o
A. Separate the particles into positive and negative charges, and increase the space between the particles
B. Separate the particles into positive and negative charges, but maintain the same space between the particles
C Decrease the velocities of the particles, and decrease the space between the particles.
D. Increase the velocities of the particles, but maintain the same space between the particles.
