Pachacha [2.7K]3 years ago
4 0

Explanation:

The melting point is the temperature at which solid substance turns to a liquid phase. However, not all substances observe this change in phase. Some sublimate- which is the turning from solid to gas without transiting the liquid phase. Such substances are; dry ice (solid CO2), arsenic, naphthalene, and iodine.

A fossil was found and determined by radiometric dating to be 11,400 years old. what is the ratio of carbon-14 to carbon-12 in t
LuckyWell [14K]

The answer would be 25%

Carbon 14 is radioactive material with 5700 year of half-time which will change it into carbon-12, a more stable substance. If the age of the fossil is 11,400 years old, then the amount of half-time passed would be: 11,400 years/ (5,700years/ half-time)= 2 half-time.

Since it undergo 2 half-time, the percentage should be: 100% * (1/2)^2= 25%
