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 depression to its cohesive energy, a (T=Ca). Since atoms near the surface have fewer bonds and reduced cohesive energy, they require less energy to free from the solid phase. Melting point depression of high surface to volume ratio materials results from this effect. For the same reason, surfaces of bulk materials can melt at lower temperatures than the bulk material. The theoretical size-dependent melting point of a material can be calculated through classical thermodynamic analysis. The result is the Gibbs–Thomson equation shown in Equation 2. formula_2 Where: T = Bulk Melting temperature A normalized Gibbs–Thomson Equation for gold nanoparticles is plotted
