Question
Chapter 16, Problem 1TE
To determine
The reason of a sample of radium always being a little warmer than its surrounding.
Expert Solution & Answer
Answer to Problem 1TE
The radium is always a little warmer than its surrounding because it emits radio active elements.
Explanation of Solution
A radioactive substance is always a little warmer than its surroundings because it decays; it releases scattering alpha or beta elements that expose internal energy to the atoms.
These substances break down into smaller constituents and disappear into various forms of energy. During this breakdown, energy is discharged in the form of heat.
The atomic number and the
Conclusion:
Therefore, the radium always a little warmer than its surrounding because it emits radio active elements.
