8. FALSE
See Paragraph 5: Heat is released every time a logical operation is performed inside a microprocessor, so the faster the processor is, the more heat it generates. Doubling the frequency quadruples the heat output.
9. NOT GIVEN
See Paragraph 9: In the future, therefore, a combination of microchannels and either thermoelectrics or paraelectrics might cool computers.
10. D
See Paragraph 6: Tweaking the processors heat sinks ?has reached its limit. So has tweaking the fans that circulate air over those heat sinks. And the idea of shifting from single-core processors to systems?also seems to have the end of the road in sight.
11. heat
See Paragraph 1: Todays high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them.
12. paraelectric
See Paragraph 3: Using commercially available paraelectric film, he and his colleagues have generated temperature drops five times bigger than any previously recorded.
13. thermoelectric
See Paragraph 7: ...the thermoelectric effect. Like paraelectric materials, this generates electricity from a heat source and produces cooling from an electrical source. Unlike paraelectrics, a significant body of researchers is already working on it.
