Arock contains uranium 238 which has a half life of 4.5 billion years. if the rock is crushed and heated, the half life in urainium-238 will

The answer is remain the same.If the rock is cut, crushed, or heated, the length of the half life of the uranium would remain the same since these factors have no effect on half-life.Even though chemical changes were affected by temperature, the physical state, pressure, concentration, the chemical environment within the molecule, and any other changing factors, the half-life of a radioactive substance is independent of these influences.

Dmight be the correct answer

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml
