The average temperature of the atmosphere has increased by 0.4°C over the last thirty years. Estimate how much energy has gone into warming up the planet in this way. Keep in mind that the atmosphere has a mass of 5 × 1018kg, and the specific heat capacity of air is about 1 Jg−1K−1.
How do we get to this answer (2×1021J)
The oxygen consumption at rest for a 70-kg person is 14.5 liter/h and that 2% of this requirement is provided by the diffusion of oxygen through the skin. Assuming that the skin surface area of the person is 1.7m2 , calculate the diffusion rate for oxygen through the skin in liter/h-cm2.
A NASA spacecraft measures the rate R at which atmospheric pressure on Mars decreases with altitude. The result at a certain altitude is:
R= 0.0915 kPa*km−1
Convert R to kJ*m−4

- The rate at which a body cools also depends on its exposed surface area S. If S is a constant, then a modification of (2), given in Section 3.1, is = KS(T-Tm), where k < 0 and Tm is a constant. Suppose that two cups A and B are filled with coffee at same time. Initially, the temperature of the coffee is 160° F. The exposed surface area of the coffee in cup B is twice the surface area of the coffee in cup A. After 30 min the temperature of the coffee in cup A is 110° F. If T = 80° F, then what is the temperature of the coffee in cup 8 after 30 min? (Round your answer to two decimal places.) °Farrow_forwardClimate change represents a global threat to the prosperity and security of humans and other species. An added element of uncertainty regarding Earth's climate future has to do with feedback loops in the climate system. One positive feedback is associated with the loss of glaciers, sea ice, and snow pack. Ice reflects about 90% of the radiant energy incident upon it, so the polar ice caps reflect significant amounts of solar energy. As the planet warms and surface ice is lost, the Earth becomes less reflective, absorbs more energy from the sun and thus heats up more rapidly. A negative climate feedback is associated with the amount of energy that Earth loses to space. As the planet warms the Stefan-Boltzmann law indicates that it will radiate more energy. Earth's average surface temperature over the 20th century was 56.7F. Since 1880 the average temperature of Earth has increased by about .830 degrees C.
