Chapter 1, Problem 1.132E

All molecules attract each other to some extent, and the attraction decreases as the distance between particles increases. Based on this idea, which state of matter would you expect has the strongest inter-actions between particles: solids, liquids, or gases?

In the left box, draw a particulate-level illustration of a substance in the gaseous state. Model the particles as spheres, which can be simple circles. Assume that the box represents a tiny, closed container that holds the particles. In the right box, draw a particulate-level illustration of the same substance after it cools and becomes a liquid

How do molecules of elements and molecules of compounds differ? In what ways are they similar?

Draw a particulate-level sketch of a heterogeneous pure substance.

If matter is uniform throughout and cannot be separated into other substances by physical processes, but can be decomposed into other substances by chemical processes, it is called a(n): A) heterogeneous mixture B)compound C) homogeneous mixture E) mixture of elements D) element

Q2. Explain the following changes in states of matter. Write two examples for each. (a) Boiling (b) Solidification

Which substance can be separated by filtration?  A. Compound B. Element C. Mixture D. Solution Which is an example of physical property of matter? * A. Baking a cake B. Cooking of gelatin C. Melting of ice D. Rusting of metal Which is an example of chemical property of matter?  A. Digestion of food B. Evaporation of water C. Sublimation of moth balls D. Condensation of water vapor       Which is a physical property of matter? A. Combustibility B. Corrosiveness C. Density D. Reactivity

Indicate whether the following sample of  matter  is a heterogeneous mixture, a homogeneous mixture, a compound, or an element. 4. a colorless gas that cannot be separated into simpler substances using physical means and that reacts with the metal a. heterogeneous mixture b. element c. compound d. homogeneous mixture

If atoms are mostly empty space and atoms compose allordinary matter, why does solid matter seem to have nospace within it?
