On average, each person in the industrialized world is responsible for the emission of 10,000 kg of carbon dioxide (CO2) every year. This includes the CO2 that you generate directly, by burning fossil fuels to operate your car or your furnace, as well as the CO2 generated on your behalf by electric generating stations and manufacturing plants. CO2 is a greenhouse gas that contributes to climate change. What is the volume, in m3, of 10,000 kg of CO2 at 20°C and 1.0 atm pressure? To put this in perspective, the volume of a typical hotair balloon is 3000 m3.

the average density of an atom is approximately 103 kg/m3. The nucleus of an atom has a radius about 10-5 times that of the entire atom, and contains nearly all the mass of the atom.  What is the approximate density, in kilograms per cubic meter, of a nucleus?

8.36 grams of a mystery substance of food with a molar mass of 149.36 g/mol is burned in a bomb calorimeter. The water in the bomb calorimeter absorbs 105,961 Joules from the burning of the substance. Calculate the heat of combustion of the mystery substance in kJ/mol. (Please input your answer as a negative number.) (DO NOT PUT UNITS IN YOUR ANSWER.) Assume that all of the heat lost by the substance is transferred to the water and no heat is lost to the surroundings.

A cylinder of gas is at room temperature (20°C). The air conditioner breaks down, and the temperature rises to 69°C. What is the new pressure of the gas relative to its initial pressure (p1)?

Small animals eat much more food per kilogram of body mass than do larger animals. The basal metabolic rate (BMR) is the minimal energy intake necessary to sustain life in a state of complete inactivity. The table lists the BMR in kilocalories per day, the mass, and the surface area for 4 animals. What is the BMR per square meter of the surface area for the mouse?

Heat Q, which has the SI unit of joule (J), is the quantity in mechanical engineering that describes the transit of energy from one location to another. The equation for the flow of heat during the time interval At through an insulated wall is KAAT Q = (Тh — T) where k is the thermal conductivity of the material from which the wall is made, A and L are the wall's area and thickness, and Th – T; is the difference (in degrees Celsius) between the high- and low-temperature sides of the wall. By using the principle of dimensional consistency, what is the correct dimension for thermal conductivity in the SI? The lowercase Greek character kappa (K) is a conventional mathematical symbol used for thermal conductivity. Appendix A summarizes the names and symbols of Greek letters. О a. (W-m)/°C O b. °C/(W. m) O c. (m . °C)/W O d. W/(m . °C)

An object has mass m, surface area A, temperature T, N molecules, and specific heat capacity c. The total thermal energy stored in the object is: Group of answer choices proportional to T^4 proportional to AT proportional to m proportional to cT proportional to NT

When it rains, water vapor in the air condenses into liquid water, and energy is released. (a) How much energy is released when 0.0318 m (1.25 inch) of rain falls over an area of 2.59×106 m² (one square mile)? (b) If the average energy needed to heat one home for a year is 1.50x1011 J, how many homes could be heated for a year with the energy determined in part (a)? (a) Number (b) Number i i Units Units >

The water is safe to drink if the number of cells falls below 10 cells/mL. It is 8 a.m. and you have 100,000 cells/mL with D being 15 minutes. You add the bleach to the tank. At what time can you release the water?  Log Nt = Log N0 – t/D.   D is the time required for a log kill.

A hot tub with a surface area of 28 ft2 is filled with water to a depth of 29 in . Hint: volume is calculated as area × height (A × h). A) What is the volume of water in the tub, in liters? Express your answer to two significant figures and include the appropriate units. B) How many kilojoules are needed to heat the water from 59∘F to 103 ∘F? Express your answer to two significant figures and include the appropriate units. C) If the hot-tub heater provides 5900 kJ/min, how long, in hours, will it take to heat the water in the hot tub from 59∘F to 103∘F? Express your answer to two significant figures and include the appropriate units.
