1. A garage floor is protected with a finishing epoxy. The epoxy is imported from a US manufacture. The
cured epoxy layer is 8.0 mm thick as measured by the contractor. If 34.1 gal of liquid epoxy was
necessary and the garage is 3.1 m wide, how deep is it (in m)?
2. A stone of mass 9.71 g is dried in an oven at 100.0°C. It is dropped in an insulated graduated
cylinder containing 50.0 mL of water at 24.0°C. The water level rises to 54.5 mL and the final
temperature after equilibrium is 33.6°C.
a) What is the density of the rock in g/cm
b) What is the specific heat of the rock?
3. An astronaut travels to the moon of a giant planet. His/her weight before departure was 715.4 N.
a) If the diameter of the moon is 5.1494 × 10° km (determined during the approach) and the mean
density of the moon is 1.88 g/cm° (determined after landing) what is the mass of the moon (kg).
