Three radioisotopes X, Y, and Z have half-lives of 1, 2 and 5 years respectively. Each of the three radioisotopes has the same activity now in July 2020. Which radioisotope will be hotter (meaning it will have more activity remaining) if you were to examine them at different times in the future, specifically in July 2023 for X, July 2024 for Y, and July 2040 for Z? Provide a full explanation of your reasoning. O Y because 2 half-lives will have passed by July 2024. O X because July 2023 is sooner than July 2024 or July 2040. O X because 3 half-lives will have passed by July 2023. O Z because July 2023 is sooner than July 2024 or July 2040. O Z because July 2040 is later than July 2023 and July 2024. O Y because July 2023 is sooner than July 2024 or July 2040. O Z because 4 half-lives will have passed by July 2040.
