A:

All physical objects, such as stars, books, people, animals, plants and the sea, are examples of matter. Matter is any physical object that occupies space and has mass.

  • Is silver magnetic?

    Q: Is silver magnetic?

    A: In its natural state, silver is not magnetic; its atoms have paired electrons that spin in opposite directions, thus causing their magnetic fields to be canceled out, making silver a diamagnetic material.

  • 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 long does it take to freeze a gallon of water?

    Q: How long does it take to freeze a gallon of water?

    A: The time it takes to freeze a gallon of water varies from minutes to several hours. The time it takes is based on several factors including temperature and the pureness of the water.

  • 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.

  • Does vinegar freeze?

    Q: Does vinegar freeze?

    A: Vinegar does freeze. The temperature at which vinegar freezes depends on the amount of acetic acid present. Common commercially-produced vinegar has a 5 percent acetic acid content and freezes at approximately 28 degrees Fahrenheit.

  • 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.

  • How much does water expand when it freezes?

    Q: How much does water expand when it freezes?

    A: Water expands by a factor of 112, or roughly 9 percent, when it freezes. Water, unlike most other liquids, forms stronger hydrogen bonds as temperatures drop. This leads to a crystal lattice structure with voids left between molecules. As the molecules arrange themselves in this manner, the substance expands and becomes less dense.

  • 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.

  • 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 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.

  • 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.

  • 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.

  • At what temperature does ice melt?

    Q: At what temperature does ice melt?

    A: Ice begins to melt when its surroundings rise above its freezing point, that being 32 degrees Fahrenheit (0 degrees Celsius). Depending on the salt content and the presence of other substances, that freezing point may be an even lower temperature.

  • What is the melting point of rubber?

    Q: What is the melting point of rubber?

    A: Rubber begins to melt at approximately 180 degrees Celsius. At low temperatures, around 5 C to 6 C, there is a risk that rubber hardens because of crystallization. The optimum temperature for rubber is 20 C.

  • What happens when water boils?

    Q: What happens when water boils?

    A: Water boils when the thermal energy in the water, which is a type of kinetic energy which causes the water molecules to move around, exceeds the strength of the hydrogen bonds between the molecules, causing them to separate from the other molecules. This breaking of bonds between water molecules consumes any additional thermal energy added, so that water at boiling temperature does not increase in temperature until the phase change is complete. In normal conditions, much of the water vapor almost immediately turns to steam, which is actually composed of droplets of liquid water because it has left the source of heat.

  • How does temperature affect the rate of evaporation?

    Q: How does temperature affect the rate of evaporation?

    A: Increased temperatures accelerate the rate of evaporation, while decreased temperatures slow down the process. First of all, heating of the liquid energizes the molecules, allowing them to escape and move into the air. Second, heat in the nearby atmosphere increases evaporation because warmer air is able to hold more water vapor.

  • 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.
