Which of the statements are NOT true about breeder reactors? (3 Answers) 1. Thorium‑232 can be used as an alternative to uranium-238 to produce plutonium-239 in breeder reactors.
2. Plutonium‑based breed reactors must be kept very hot (>800 °C) to operate efficiently.
3. Breeder reactors are less prevalent than ordinary fission reactors.
4. Uranium‑238 is bombarded with neutrons to produce plutonium-239 in breeder reactors.
5. Water is often used as a coolant for breeder reactors.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
