Biofilms allow microbes to coordinate responses within an environment, making the community much more durable than single free-floating bacteria.

A refrigerator has a coefficient of performance equal to 4.2. How much work must be done on the refrigerator in order to remove 250 J of heat from the interior? (a) How much work is done on the gas in each cycle? (b) How much heat is exhausted into the hot reservoir in each cycle?

A heat engine performs the reversible cycle abca with 9.0 moles of an ideal gas, as shown in the figure. Path ca is an adiabatic process. The temperatures at points a and b are 300 K and 500 K, respectively. The volume at point c is 0.20 m3. The adiabatic constant of the gas is 1.60. What is the thermal efficiency of this engine?      η=

When an ideal gas increases in volume at constant pressure, the average kinetic energy of the gas molecules
