The correct option is A) 1/8


half-life of tritium, or hydrogen-3, is 12.32 years.      

After about 37 years,

= 37/12.32

= 3

means 3 half lives.


sample of tritium that will remain unchanged will be:

= 1/2^no.of half lives

= 1/2³

= 1/2 x 1/2 x 1/2 = 1/8

<u> 1/8 remains back</u>

What happens to the speed of motion of the particles of a gas when a certain volume of the gas is heated at constant pressure? E
Vitek1552 [10]
As the gas is heated, the particles will begin to move faster. Likewise if you start to cool a gas, the particles will move slower. Because the gas remains at a constant pressure and volume, the particles cannot spread out so they simply move around the container even faster.

Hope this helps :)
