Fresh water freezes at 32 degrees Fahrenheit, which is 0 degrees Celsius and 273.15 degrees on the Kelvin scale. Seawater freezes at a slightly lower temperature than fresh water due to its high salt content.Know More
Although water has standard freezing temperatures, scientists have found water in its liquid form at temperatures below -40 degrees Fahrenheit. As water grows colder, its molecular structure changes shape, which alters the density of the water and increases its heat capacity. At -55 degrees Fahrenheit, the molecules become tetrahedrons, and that difference in structure changes the way the molecules react to heat and cold.
All things freeze at 0 degrees Kelvin, also known as Absolute Zero. That temperature represents a total absence of heat, and molecular motion stops.Learn More
The patent for the process to make what people now know as gasoline was filed in 1913. The forerunner of gasoline was around in the 1800s before the invention of the internal combustion engine, but it was only known as a useless by-product of the process used to make kerosene for oil lamps.Full Answer >
The element that has the largest atomic radius is cesium. It has an atomic radius of 298 pm, or picometers. An alkali metal, cesium is so active that it instantly explodes if dropped into cold water. It's also one of the few metals that becomes a liquid at close to room temperature. Its melting point is 83.19 degrees Fahrenheit.Full Answer >
An element is a description of a type of atom, so a single atom is representative of an element but not an element itself. "An atom" refers to a physical entity; "an element" refers to a type of atom.Full Answer >
The mass of NaCl present in a 1 molar solution of NaCl in water depends on the volume of the solution. For example, 1 liter of solution contains 58.44 grams NaCl. The mass of the solute is directly proportional to the volume of solution.Full Answer >
