In Table 7.2 (Energy Expenditure of a 180-Pound Person During Selected Exercises)Links to an external site. in the course textbook, it is claimed that a person climbing stairs expends about 1200 kcal/hr. The maximum human power output for short-term effort is approximately 1200 W (remember 1 W = 1 J/s). Is the value of 1200 kcal/hr a reasonable estimate of average power output by a person climbing stairs? Note: Power is defined as energy per time, so 1200 kcal/hr has units of energy per time. A watt is the SI unit of power and has units of J/s. So to approach this problem you will need to convert one power measurement into the other. Group of answer choices It comes out to be 1400 W, which is too high It is impossible to convert kcals into joules since one is an SI unit and the other isn't It comes out to be 1.395 x 103 W, so the value in the table seems reasonable It comes out to be 960 W, that is too high It comes out to be 1.4 W and that is too low
Consider a cloudless day on which the sun shines down across the United States. If 2667 kJ of energy reaches a square meter (m2) of the United States in one hour, how much total solar energy reaches the entire United States per hour? The entire area of the United States is 9,158,960 km2.
Can you please type out the answer, don’t write it on paper!
According to the Law of Conservation of Energy (Laws of Thermodynamics) Energy in a system is always decreasing until it reaches absolute zero. Enthalpy is always increasing even though the energy is transforming. Energy can transform but the total energy of a system is constant. Energy is a constant and cannot be altered. Energy is always present but cannot be measured.
A 100-W lightbulb is placed in a cylinder equipped with a moveable piston. The lightbulb is turned on for 0.020 h, and the assembly expands from an initial volume of 0.90 L to a final volume of 5.88 L against an external pressure of 1.0 atm. You may want to reference (Pages 370 - 373) Section 9.3 while completing this problem. Part A Use the wattage of the lightbulb and the time it is on to calculate the heat transferred, q, in joules. (Assume that the cylinder and lightbulb assembly comprise the system and assume two significant figures.) Express your answer using two significant figures.

Top 7 Renewable Energy Sources in 2020 SOLAR ENERGY Wind ENERGY BIO OCEAN ENERGY HYFROGEN ENERGY GEOTHERMAL ENERGY POWER HYDRO POWER 13. What sectors produce the most carbon dioxide emissions? (Write in order #1, #2..)|
Biofuels such as wood generate carbon dioxide when they are burned, but biofuels are nonetheless considered a partial solution to climate change. Why? Because plants take carbon dioxide out of the air as they grow, and burning them puts the same amount of carbon dioxide back into the atmosphere, so they are "carbon neutral". Because biofuels are more expensive than fossil fuels, so people will use less of them and generate less carbon dioxide. Because wood and other biofuels contain only a small amount of carbon, so they do not generate very much carbon dioxide when burned. Because wood and other biofuels generate a lot of ash when they burn, and this ash in the atmosphere cools down the Earth.
Please help me with this chemistry question, please include citations/references. Thank you! Discuss and explain at least two problems associated with the burning of fossil fuels. Is fossil fuel finite? What is its origin? What are two examples of some environmentally friendly renewable energy resources?
A sample of 2.30 g of potato chips was burned in a calorimeter. The calorimeter was calibrated to have a heat capacity of 6.94 kcal/°C. The heat released caused the temperature of the calorimeter to increase 1.75°C. Calculate the food caloric content of the potato chips in nutritional calories per gram to three significant figures. Recall that 1 nutritional calorie (Cal) = 1 kcal.
