The energy released from condensation in thunderstorms can be very large. Calculate the energy (in J) released into the atmosphere for a small storm of radius 2.1 km, assuming that 2.7 cm of rain is precipitated uniformly over this area. (Assume that the rain is precipitated over a circular area and that the density of water is 1000 kg/m3.)

A gas expands from I to F in the figure below. The energy added to the gas by heat is 212 J when the gas goes from I to F along the diagonal path. Three paths are plotted on a PV diagram, which has a horizontal axis labeled V (liters), and a vertical axis labeled P (atm). The green path starts at point I (2,4), extends vertically down to point B (2,1), then extends horizontally to point F (4,1). The blue path starts at point I (2,4), and extends down and to the right to end at point F (4,1). The orange path starts at point I (2,4), extends horizontally to the right to point A (4,4), then extends vertically down to end at point F (4,1). (a) What is the change in internal energy of the gas? Use the relations between various features of the graph and the work done on the gas to find the energy added by work and then use your result to find the change in internal energy of the gas. J(b) How much energy must be added to the gas by heat for the indirect path IAF to give the same change in…

Compute the energy consumption in units of joules per year, gigawatts (GW), and watts per person as (a) fuel, (b) food, and (c) solar radiation for a country of population density 20 person/km2, an area of 1 million km2, and a fuel energy consumption rate of 250 GJ per person per year. Solar radiation reaching the ground is approximately 150 W/m2. The average person consumes food containing 2000 “calories” per day (1 calorie = 4182 J).

A certain sandwich cookie contains 55 CC of nutritional energy. For what amount of time must you swim in order to work off three cookies if swimming consumes 510 C/hC/h AND Instead of swimming you decide to run for 40 min at a pace that works off 860 C/hC/h. How many cookies have you worked off?

One gram of water is vaporized into 1.65×103 cm3 when boiled at a constant pressure of 1.013×105⁢P⁢a. If the heat of vaporization at this pressure is Lv=2.256×106⁢J/k⁢g, what is the work done by the water when it vaporizes?
