2. Read and record the temperature of the gas using the thermometer attached to the container.

This lab experimented with temperature and gas according to Charles’ Law, which states that gas will expand when heated. The results indicated that Charles’ Law is indeed applicable to this lab. The data concluded that the volume did

8.When the reaction is completed, record the volume of gas in the graduated cylinder. Record observations about which reactant was the limiting reactant.

If the volume of the combustion container is 10.0 L, calculate the final pressure in the container when the temperature is changed to 110.° C. (Assume no oxygen remains unreacted and that all products are gaseous.)

Assuming no viscous forces present an inviscid model has been used for the calculations. Also from the equation of the Reynolds number Re=ρvl/μ due to Re being really big rearranging and assuming v and l to be constant the viscous force μ =ρvl/Re becomes negligible.

Since the Bi value of the aluminum system is less than 0.1, convection from the water to the surface of the cylinder is the rate limiting heat transfer mechanism. Thus, a lumped-parameter analysis can be safely applied. The Plexiglas system, on the other hand, has a Bi >> 0.1, and the rate limiting mechanism is conduction in the cylinder.

The lid-driven cavity flow is most probably one of the most studied fluid problems in the
