Solar panels on the roof aren't just clean power; they are the house. Using thermal imaging , researchers determined that during the day, a building's ceiling was 5 degrees Fahrenheit cooler under solar panels than under an exposed roof. At night, the panels help hold heat in, A __ As solar panels sprout on e an increasing number of residential and commercial roofs, it becomes more important to consider their impact on buildings' total energy costs. Data for the study was gathered over three days on the roof of the San Diego School of Engineering with a thermal infrared camera. The building is equipped with tilted solar panels and solar panels B __ . Some portions of the roof are not covered by panels. The panels essentially act as roof shades. Rather than the sun beating down onto the roof, C __ , photovoltaic panels take the solar beating. Then much of the heat is removed by wind blowing between the panels and the roof. The benefits cooling.Also,the more efficient the s solar panels, the bigger the cooling effect .For the are greater if there is an open gap D __ , so tilted panels provide more building researchers analyzed , the panels reduced the amount of heat reaching the roof by about 38 percent. Although the measurements took place over a limited period of time the team devel- oped a model that allows them to extrapolate their findings to predict cooling effects throughout the year. For example, in winter the panels would keep the sun from heating up the building. But at night, they would also keep in E __ There are more efficient ways to p passively cool buildings __ But, if you are considering installing solar photovoltaic, depending on your roof thermal properties, you can expect a large reduction in the amount of energy you use to cool your residence or business. 1. which causes heat to be pushed through the roof 2. where air can circulate the building and the solar panel 3. that are flush with the roof 4. such as reflective roof membranes 5. reducing heating costs in the winter 6. that was not covered with panels 7. whatever heat accumulated inside
- Given that stars and planets initially form from the same gas and dust in space, some astronomers have posited that host stars (such as the Sun) and their planets (such as those in our solar system)are composed of the same materials, with the planets containing equal or smaller quantities of the materials that make up the host star. This idea is also supported by evidence that rocky planets in our solar system are composed of some of the same materials as the Sun. A Mark for Review Which finding, if true,would most directly weaken the astronomers' claum? A Most stars are made of hydrogen and helium, but when cooled they are A revealed to contain small amounts of iron and silicate. B A nearby host star is observed to contain the same proportion of B hydrogen and helium as that of the Sun. C Evidence emerges that the amount of iron in some rocky planets is considerably higher than the amount in their host star D The method for determining the composition of rocky planets is discovered to beless effective when used to analyze other kinds of (D) planets.
