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.

Several different factors can also cause ice to begin melting, even at very low temperatures. Adding salt or even sugar causes normally stable ice to begin melting, either until the added substance is sufficiently diluted or the surrounding temperature lowers to the freezing point of the new solution. Convection currents of either air or water can also speed the rate at which ice melts.

    At what temperature does soda begin to freeze?

    A:

    The freezing point of soda is slightly lower than the freezing point of water, which is 32 degrees Fahrenheit. Carbon dioxide is added to soda to give it its fizz, and carbon dioxide lowers the freezing point of water.

  • Q:

    What makes ice melt?

    A:

    Heat causes ice to melt. Ice returns to the liquid state when the temperature rises above the freezing point of water, which is 32 degrees Fahrenheit or 0 degrees Celsius. Additionally, because of the specific and unusual characteristics of water, increased pressure causes it to melt as well.

  • Q:

    How long does it take ice to melt?

    A:

    It takes between 10 to 12 minutes to completely melt an ice cube on concrete with an ambient temperature of 109 degrees Fahrenheit. Ice melts at different speeds based on a range of factors such as the temperature of the ice, the size of the ice and the ambient temperature.
