Use exercise 58 as an analogy to describe what occurs in exercise 59. Does it make to think that the alcohol is made of very tiny particles (molecules) rather than being an infinitely continuous material?
Exercise 58: A skillet is lined with a thin layer of cooking oil followed by a layer of unpopped popcorn kernels. Upon heating the kernel, all pop, thereby escaping the skillet. Identify any physical or chemical changes.
Exercise 59: A cotton ball is dipped in alcohol is wiped across a tabletop. Would the resulting smell of alcohol be more or less noticeable if the tabletop were much warmer? Explain.

They left behind a liter of shimmering blue substance. This substance is liquid at room temperature, but when you place it in a refrigerator it turns to a shimmering blue solid. When you take it back out of the refrigerator, it turns into a shimmering blue liquid again. What kind of change (chemical or physical) most likely occurred? Explain why to support your answer. Use evidence from the text to support your answer.arrow_forwardWhich one of the following statements best supports the idea that matter is made up of particles? Metals expand when heated. if a bottle of perfume is opened, the smell spreads quickly. Water always fills the space available to it. Gases are usually lighter than liquids. Which of the following is NOT a property of a compound? It can be broken down into simpler substances. It consists of multiple phases. It has definite temperature. It has a uniform appearance. Water behaves like most other molecules in all ways, except that ________. It interacts strongly with other water molecules. It can exist as a solid, liquid, or gas. Its temperature correlates with how rapidly its molecules are moving. Water in an open container is absorbed by the container, disappears, changes into air, or dries up, and goes into the air. 4.Which of the following provides evidence that air is a mixture? Living organisms breathe in oxygen. Nitrogen and oxygen are both gases. Substances burn in the…arrow_forward
