States of Matter

A:

Dry wood catches fire between about 300 degrees Fahrenheit and 580 degrees Fahrenheit, depending upon the species of wood and the extent of decay present, with more decayed wood being quicker to ignite. The amount of moisture in the wood is the strongest influence on wood reaching this temperature.

  • What Happens When Water Vapor Cools?

    Q: What Happens When Water Vapor Cools?

    A: When water vapor cools, it condenses. It is a phase change where water changes from a gas to a liquid. Condensation is the opposite of evaporation.

  • What Is It Called When a Gas Turns Into a Liquid?

    Q: What Is It Called When a Gas Turns Into a Liquid?

    A: Condensation is the name of the process through which gas turns into a liquid. Three common states of matter exist: solids, liquids and gases. Matter, however, can change its state with the addition or subtraction of energy. The energy is usually in the form of heat.

  • What Goes up and Never Comes Down?

    Q: What Goes up and Never Comes Down?

    A: The most accurate answer to what goes up and never comes down is a person's age. Another common answer is a person's height. Heat and smoke are also accurate answers for what goes up and never comes down, due to the fact that heat rises.

  • Where Does Chalk Come From?

    Q: Where Does Chalk Come From?

    A: According to Discovering Fossils, chalk occurs naturally in nature as calcium carbonate, a form of limestone. Limestone is formed from the decomposition and sedimentation of Coccolithophores skeletons, a type of plankton.

  • What Happens in a Condensation Reaction?

    Q: What Happens in a Condensation Reaction?

    A: In a condensation reaction, two reactants react to form water or ammonia and one other byproduct. As long as either water or ammonia is formed and is the only byproduct, a reaction is considered a condensation reaction. A condensation reaction is not to be confused with the process called condensation, where water vapor turns to liquid after losing heat.

  • How Does Matter Change From One State to Another?

    Q: How Does Matter Change From One State to Another?

    A: An element's state changes depending on its temperature and the pressure exerted on it. Heating or cooling an element can cause it to change states. Adding or removing pressure can do so as well.

  • What Are Characteristics of a Solid?

    Q: What Are Characteristics of a Solid?

    A: Solids hold their shape and have a fixed volume. The molecules in solids are packed closely together and cannot be moved. Solids also have slow diffusion and low vapor pressure.

  • Can a Solid Turn Into a Gas?

    Q: Can a Solid Turn Into a Gas?

    A: A solid can turn directly into a gas through a process called sublimation. In this instance, the solid vaporizes without going through the intermediary liquid stage. For example, in the water cycle, this would involve snow or ice turning directly into water vapor without going through the melting process. The opposite process, in which vapor changes into ice, is known as deposition.

  • What Are the Characteristics of Matter?

    Q: What Are the Characteristics of Matter?

    A: All physical matter has mass, weight, volume and density. Matter also has certain characteristics restricted only to specific physical states. Physical matter is made up of atoms, minuscule particles that form physical structures via their electrically charged attraction to one another.

  • What Is the Density of Oil?

    Q: What Is the Density of Oil?

    A: The density of oil depends on the type of oil and varies between 0.8 to 0.96 grams per centimeter cubed. Fuel oil is commonly used in engines and industrial furnaces. It is also called heating oil and has a density of 0.81 grams per centimeter cubed.

  • Why Can Gases Be Compressed?

    Q: Why Can Gases Be Compressed?

    A: Gases can be compressed because each gas particle has relatively vast amounts of room between it and all other gas particles the majority of the time. Thus, compression, which is essentially forcing the gas particles closer together, has a great deal of space to reduce. This contrasts with liquids and solids, which have particles in constant contact with one another, and thus little room to compress.

  • How Does Gas Become a Liquid?

    Q: How Does Gas Become a Liquid?

    A: The process of a gas changing to a liquid is called condensation, and for condensation to take place, the environment has to reach maximum vapor pressure, generally through a lowering of temperature in the case of the water cycle. Because pressure varies inversely with temperature, as temperature decreases, pressure goes up, causing the gas molecules to move with progressively less kinetic energy. Eventually, liquid vapor and droplets form, and the gas begins to condense.

  • Does Ice Weigh More Than Water?

    Q: Does Ice Weigh More Than Water?

    A: In general, if ice and water have the same volume, then the ice weighs less. This is because ice is less dense than water and occupies more space. Therefore, a gallon of ice weighs less than a gallon of water.

  • What Is the Difference Between Steam and Water Vapor?

    Q: What Is the Difference Between Steam and Water Vapor?

    A: The difference between steam and water vapor is that water vapor is typically the same temperature as the air that is present while steam is above the boiling point of water. The chemical composition of water and steam are identical.

    Q: What Is the Melting Point of Glass?

    A: The melting point of glass varies greatly according to what type of glass is being melted, but typically ranges from 2,597 to 2,912 degrees Fahrenheit. The variance in melting temperatures is caused by the mix of materials used initially to create the glass.
