Quiz 2: States of Matter

When methane gas reacts with oxygen in the air, it burns to produce water vapor and carbon dioxide gases, as well as heat and light. Which underlined components of this process are matter and which are not matter?

Place each term under the matter or non-matter category.

Place each description underneath the category that BEST fits the description. (Note: There may be multiple descriptions in one category or none at all in a category!)

Gallium is a metal with a melting point of 86^oF. A student walks into the science room and sees a shiny silver piece of gallium sitting on a table. The student picks it up and holds it in their hand, which is approximately body temperature, 98.6^oF. After a while, the piece of gallium becomes a shiny silver pool in the palm of their hand. Explain what happened and why. (Be detailed by explaining changes in heat energy, particle movement or speed, and spacing)

One of Dr. Jill’s kids favorite treats are frozen bananas and ice in a smoothie! It’s simple to make too. You just put bananas in the freezer and then add the bananas and ice to a blender, mix together into a smoothie that becomes a perfect combination of half solid and half liquid and you’re done! Halfway through eating the smoothie, Dr. Jill’s son Mateo gets sad because it isn’t frozen anymore and he says it’s no longer thick and it’s warm…. yuck! :(

Complete the particle diagrams in the containers below to visually represent what is occurring at the particle level during this process. Be sure to include the energy, movement or speed, and spacing of the particles in each diagram. NOTE: You can draw this on paper and take a picture.

(Draw 1 type of particle, “smoothie,” to represent the banana/ice mixture, 

such as circles only. You don’t need to draw the bananas separate from the ice such as circles and triangles.)

Explain how the smoothie changes over time to no longer taste good to my son’s liking! Describe changes in energy, movement or speed, and spacing of molecules.
