That a supercooled gas eventually phase separates is consistent with the 2nd Law of Thermodynamics because the phase separation lowers the Helmholtz free energy of the system
Aluminum has a specific heat of 0.900 J/g·°C. How much energy is required to raise the temperature of 160. g of aluminum from 20.0°C to 183.0°C?
Consider 2 moles of a onoatomic ideal gas (Cv,m=3R/2) at an initial pressure of 2.0 atm and an initial temperature of 298 K. Assume it expands adiabatically and reversibly until its volume doubles. calculate the expansion ork, the final tmperature..
Wastewater flow in a sewer can be estimated by adding a known amount of tracer such as salt solution and measuring the salt concentration upstream and downstream of the point of addition.
If 25.00 mL of 0.687 M Fe(NO3)2 are added to a flask containing 0.289 g of aluminum metal, what compounds will be present in the flask once the reaction is complete? (Ignore water, etc.)
A steel cylinder is filled with 5.75 mol of nitrogen at 22degrees Celcius. The volume of the cyclinder is 18.4 L Calculate pressure inside the cylinder.
When 24 copper pennies are submerged in water, the pennies displace 8.26 cm3 of water. If the combined mass of the pennies is 73.86 g, what is the density of copper?
