Comparing Decay Counts and Heat
Base your answers on the information provided and your knowledge of chemistry. Use the 2025 Chemistry Reference Tables as needed.
A nuclear simulation records every decay in two containers during an equal observation interval. It also calculates the energy deposited in each container. In the model each decay in a given container deposits the stated amount of energy, and the container records all of it.
| Container | Decays counted | Energy deposited per decay (model units) |
|---|---|---|
| P | 24 | 2 |
| Q | 12 | 4 |
Question 1
Which container has more decay events during the interval?
- P only
- Q only
- They have the same count.
- Only energy can be compared.
Question 2
Calculate and compare the deposited energies for P and Q.

A third container deposits 48 energy units. It contains only one of the two decay types, but its event counter is turned off.
Question 4
Give the two decay counts that fit the third container’s energy reading. Explain what additional evidence would distinguish them.
