States of Matter

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.

  • 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.

  • 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.

  • 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.

  • What is the melting point of mild steel?

    Q: What is the melting point of mild steel?

    A: The melting point of mild steel, or low carbon steel, is usually 2,600 degrees Fahrenheit, or 1,427 degrees Celsius. Mild steel is one of the most commonly used types of industrial steel, and it consists of an alloy of steel and carbon.

  • At what temperature does wood start to burn?

    Q: At what temperature does wood start to burn?

    A: When wood is completely dry and is not a type of artificial wood, the combustion temperature is generally 451 degrees Fahrenheit, according to the Argonne National Laboratory. However, there are many variables, such as moisture, oxygen ability and wood density, that come into play.

  • Why do solids have definite shapes and volumes?

    Q: Why do solids have definite shapes and volumes?

    A: Solids have definite shapes and volumes because their atoms and molecules are held together firmly by the strong inter-molecular forces. At low temperatures, the kinetic energy in the solid is usually not enough to overcome these intermolecular forces, so the solid remains in the same state.

  • What is the temperature of ice?

    Q: What is the temperature of ice?

    A: Chemists at the University of Utah discovered that ice forms at temperatures as low as minus 55 degrees Fahrenheit, according to a Science Daily article. Prior to this discovery, scientists believed ice formed exclusively at 32 degrees Fahrenheit.

  • At what temperature does wood catch fire?

    Q: At what temperature does wood catch fire?

    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 are some general properties of matter?

    Q: What are some general properties of matter?

    A: Properties of matter, defined by Education Portal, are divided into two groups: physical properties that include color, density, mass, boiling point, volume, solubility, malleability and temperature; and chemical properties that include reactivity with oxygen, reactivity with water, flammability, pH, toxicity and combustion. Physical properties of matter can be observed or measured without changing the composition, while chemical properties can only be observed after a chemical change has occurred.

  • 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.

  • 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.

  • What is the boiling point of milk?

    Q: What is the boiling point of milk?

    A: The additional molecules in milk keep its boiling point slightly higher than water, which boils at 100 degrees Celsius or 212 degrees Fahrenheit. The chemical composition of milk dictates the boiling point and so there is no standard boiling point.

  • At what temperature does gasoline burn?

    Q: At what temperature does gasoline burn?

    A: Gasoline burns at 495 degrees Fahrenheit at standard atmospheric pressure. This ignition temperature is the lowest temperature at which gasoline may undergo combustion. If the temperature is lower than this, a fire is needed to ignite gasoline. If too little air is present, a higher temperature is needed.

  • 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.

  • 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.

    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.
