Q:

Why does ice cream melt?

A:

Quick Answer

Ice-cream melts because it is heated by the objects and air touching it and its melting point is much lower than room temperature. Heat is the transference of thermal energy. Thermal energy is the average amount of movement, or kinetic energy, of the particles within an object.

Full Answer

The greater the thermal energy of an object, the hotter it is. When an object with lesser thermal energy comes in contact with an object of greater thermal energy, such as when ice-cream comes in contact with room-temperature air, thermal energy is transferred from the object with more thermal energy, the air, to the object with less thermal energy, the ice-cream, until the energy is equal. However, the amount of energy required to raise the temperature of an object, known as specific heat, differs between objects. This is why some objects, such as many metals, feel hotter or colder than the objects around them even though they possess the same amount of thermal energy.

    What are some physical properties of chlorine?

    A:

    At room temperature and normal atmospheric temperature, chlorine is a yellow-green gas that has a density heavier than air. Lowering the temperature to minus 29 degrees Fahrenheit or increasing the pressure converts it to a yellow liquid. Chlorine is highly reactive and does not exist as a pure compound in nature.

    What is mercury cyanide?

    A:

    Mercury cyanide, or Hg(CN)2, is an odorless white powder at room temperature that is extremely poisonous if inhaled, touched or ingested. If mercury cyanide burns in a fire, toxic nitrous oxides are formed in smoke clouds. When mixed with water, mercury cyanide gradually produces the flammable gas hydrogen cyanide. Protective gear such as rubber gloves, dust masks and goggles are necessary to handle mercury cyanide.

  • Q:

    What happens when you mix hydrogen and oxygen?

    A:

    Mixing hydrogen and oxygen equals water, but at room temperature and normal pressure this happens extremely slowly; an energy source, a catalyst, is needed to start the chemical reaction. However, hydrogen is extremely flammable and explodes even in the presence of a lighted match or a spark, so attempting this is not advised.
