q1 = heat to warm water from 10 to 100.
q1 = mass x specific heat x (Tfinal-Tinitial) where Tf is 100 and Ti is 10 (or delta T = 90).
q2 = heat to vaporize liquid water at 100 to vapor at 100 C.
q2 = mass water x heat vaporization
Total q = q1 + q2.
Which is faster, a bullet with a velocity of 1100. feet per second, or Superman traveling at 1100. miles per hour? Provide the correct velocity for either Superman or the bullet in scientific notation with the correct number of sig figs. You must use the following conversion factors: Density = m/V; 1 L = 1000 mL; 1 L = 1.057 quarts; 1 gallon = 4 quarts; 1 mile = 5280 feet; 1 foot = 12 inches; 1 inch = 2.54 cm; 1 meter = 100 cm; 1 kilometer = 1000 m; 1 g = 0.03527 oz; 1 lb = 16 oz
