Water at 20 degrees Celsius is placed on a stove. As the water is heated, thermal energy is absorbed by the water. If the water is heated to a

maximum temperature of 80 degrees Celsius, what happens as a result of

the increased temperature?

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).
