Which actinide, discovered by Glenn T Seaborg in 1940, is used as a heat source for sensitive electrical components in satellites as well as a power source for satellites?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Plutonium.
- Heat Source for Satellites: Plutonium-238, a specific isotope of plutonium, is used as a heat source in space missions.
- It is used in Radioisotope Thermoelectric Generators (RTGs) to provide power and heat to spacecraft.
- The heat generated from the radioactive decay of plutonium-238 is converted into electrical energy, which is crucial for the operation of sensitive electrical components and instruments on satellites and space probes.
- Power Source for Satellites: RTGs are used in space missions where solar power is not feasible, such as deep-space probes or missions to outer planets.
- Plutonium-238's long half-life and high energy density make it an ideal power source for these applications.
