Answer :
Final answer:
1 kg of Uranium-235 can keep a 100-watt light bulb running for approximately 8 x 10^11 hours, given that all emitted energy is converted into electricity.
Explanation:
The question asks how long 1kg of uranium-235 can power a 100-watt bulb. The energy released from 1 kg of Uranium-235 through fission is approximately [tex]8 x 10^13[/tex] watt-hours. Therefore, to find out how long this energy can power a 100-watt light bulb, you divide the total energy by the bulb's wattage.
Steps:
- Convert 1 kg of Uranium-235's energy release to watt-hours: 1 kg[tex]U-235 = 8 x 10^13[/tex] watt-hours
- Divide the total watt-hours by the bulb's wattage: [tex]8 x 10^13 watt-hours / 100 watts = 8 x 10^11[/tex]hours
1 kg of Uranium-235 can keep a 100-watt light bulb burning for 8 x 10^11 hours, given a perfect energy conversion.
