Qubit (game show) lustrous metal is the seventy-fourth element on the periodic table?" If the contestant answers incorrectly or passes, the host reads a clue such as: "Its chemical symbol is W, which stands for" Wolfram, "the German name of this element." If the contestant still answers incorrectly or passes, the host reads two choices, such as: "Is it platinum or tungsten?" Tungsten is the correct answer. The other answer is changed if necessary so it is not an answer already tried by the contestant. If the constant still answers incorrectly at this point, a 10-second time penalty is applied. The contestant with
Melting point graphically to the right, but also of Si, Ge, Ga, Bi. With extremely large changes in pressure, substantial changes to the melting point are observed. For example, the melting point of silicon at ambient pressure (0.1 MPa) is 1415 °C, but at pressures in excess of 10 GPa it decreases to 1000 °C. Melting points are often used to characterize organic and inorganic compounds and to ascertain their purity. The melting point of a pure substance is always higher and has a smaller range than the melting point of an impure substance or, more generally, of mixtures. The higher the
