(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The polonium isotope 210Po, an alpha emitter, has a half-life of 138.38 days. You happen to have a 1.5 g cube of 210Po, so you decide to use it to boil water for tea. You fill a well-insulated container with 120 mL of water at 18° C and drop in the cube of polonium.

(a) How long will it take to bring the water to a boil?

(b) Explain whether or not the water have been altered in any way by this method of boiling.

2. Relevant equations

N=N_{0}e^{-λt}

E=mc^{2}

E=mΔTC

where c is heat capacity of water 4.18 j/gC°

3. The attempt at a solution

So far I have found the energy fro the water to change from temperature which is 41131.2 joules. Then I feel i would have to find the amount of time it takes polonium to reach that amount of energy but i dont know how i would do that.
