How much energy does Hannah the Standard Poodle absorb from the sun during a 37-minute walk? Hannah’s fur is matte black, so she absorbs nearly all of the sunlight that hits her; from above, she looks approximately like a rectangle that is 92 cm long and 32 cm wide. The solar intensity in Hannah’s Orange County neighborhood is 1200 W/m2.

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?

In an old house, the heating system uses radiators, which are hollow metal devices through which hot water or steam circulates. In one room the radiator has a dark color (emissitivity = 0.871). It has a temperature of 68.6 °C. The new owner of the house paints the radiator a lighter color (emissitivity = 0.497). Assuming that it emits the same radiant power as it did before being painted, what is the temperature (in degrees Celsius) of the newly painted radiator?

A cup of hot coffee sits on your desk. Assume that the thermal energy in the coffee can be converted with an efficiency of 100%% to gravitational potential energy of the coffee-Earth system-enough so that the coffee rises up above the rim of the cup. Let the height of the coffee rise by 3.4 cm. Find the magnitude of the drop in temperature needed to accomplish this energy conversion. Use c = 4180 J/kg⋅C for coffee.
Frosty the Snowman’s magic hat keeps him at a comfortable temperature of -11°C. However, a nearby test of a nuclear explosive device knocks off his hat and irradiates him. He absorbs 47 MJ of energy! Frosty’s initial mass is 99 kg of pure ice. Ignore the hat and any other ornaments. We need to determine if Frosty absorbs sufficient energy to melt completely. What is the minimum amount of energy, in megajoules, that is required to melt Frosty?
