Answer is: A. the rate of decay for certain isotopes.

For example, radiocarbon dating is called Carbon-14 dating.

Carbon-14 is a radioactive isotope of carbon, with a half-life of 5730 years.

Carbon bound in fossil fuels has different isotopes than carbon in atmosphere. Fossil fuels are underground and cosmic rays do not affect carbon in them same as atmosphere carbon. Carbon in fossil fuels that is underground longer than ten thousand years has only C-12 isotope and not C-14.

If 0.507J of heat leads to a 0.007 degree C change in water, what mass is present?
Mamont248 [21]

Answer:

17.3 g

Explanation:

<u>Given the following data;</u>

  • Quantity of heat, Q = 0.507 J
  • Temperature = 0.007°C
  • Specific heat capacity of water = 4.2 J/g°C

Mathematically, Heat capacity is given by the formula;

Q = MCT

Where;

  • Q represents the heat capacity or quantity of heat.
  • M represents the mass of an object.
  • C represents the specific heat capacity of water.
  • T represents the temperature.

Making "M" the subject of formula, we have;

M = \frac {Q}{CT}

Substituting the values into the formula, we have;

M = \frac {0.507}{4.2*0.007}

M = \frac {0.507}{0.0294}

<em>Mass, m = 17.3 grams</em>
