← ScienceWhich outcome increases within a sample containing unstable isotopes?
A)Probability of radioactive decay events✓
B)Overall specific heat capacity value
C)Material resistance against tensile stress
D)Tendency to form crystalline structures
💡 Explanation
Radioactive decay increases with unstable isotopes because it undergoes nuclear transmutation via quantum tunneling, rather than remaining stable. Therefore, decay probability increases; rather than specific heat changes, which relies on kinetic energy.
