King Tut's reign came to an end at 3350 years ago
<h3>Further explanation</h3>
Carbon-14 is a radioactive isotope that can decay. This isotope can be used to determine how long ago an organism died by knowing the ratio from 12C to 14C
Can be formulated
Or we can use :
The half-life of C-14, 5730 years, so the decay constant :
Assume the initial C-14 activity was 13.6 disintegrations/min/g of C
Answer:
a) The heat which we supply to water during boiling is used to overcome these forces of attraction between the particles so that they become totally free and change into a gas. This latent heat does not increase the kinetic energy of water particles and hence no rise in temperature takes place during the boiling of water.
b) Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.
