The Curiosity rover landed on Mars on August 6, 2012, and is currently exploring the surface. Curiosity uses a radioisotope thermoelectric generator (RTG) to provide power for all operations. The Curiosity RTG has a maximum output of 110 watts [W], and loses 2000 watts [W] as heat. By comparison, Viking 1 spacecraft launched in 1975. The Viking 1 has an input power of 0.75 horsepower [hp] and loses 525 watts [W] to heat. Which device is more efficient?
A cube of edge length 6.0 * 10-6 m, emissivity 0.75, and temperature -100C floats in an environment at -150C.What is the cube’s net thermal radiation transfer rate?

- A. The planet Venus is different from the earth in several respects: (a) it is only 70 % as far from the sun, so the solar constant is 2800 W/m²; (b) its thick clouds reflect 77% of all incident sunlight and (c) its atmosphere is much more opaque to infrared light. B. (i) Estimate what the average surface temperature of Venus would be if it had no atmosphere and did not reflect any sunlight. (ii) Taking into account the reflectivity of the clouds, estimate the surface temperature.

- What is the role of “loose” electrons in heat conductors? (A) Loose electrons move quickly away from hot locations, making it impossible for energy to move and making the object a good insulator.

(D) Loose electrons transfer energy rapidly through a solid.arrow_forwardYou recently bought an aluminum (C = 0.9 J/g-K) kettle with a mass of 2 kg. You used the kettle to heat water (C = 4.184 J/g-K). The kettle contains water (1.5 kg). The kettle was heated using an induction stove from 20°C to 85°C. The water is then used for coffee.
