Final answer:
To increase the likelihood of obtaining accurate results in determining the melting point of a new substance, the scientist should use precise measuring equipment, repeat the experiment multiple times, and maintain a controlled environment.
Step-by-step explanation:
In order to increase the likelihood of obtaining accurate results in determining the melting point of a new substance, the scientist should follow a few actions:
- Use precise and calibrated measuring equipment to ensure accurate measurements of temperature and substance quantity.
- Repeat the experiment multiple times to account for any variability or errors in the process.
- Use a controlled and stable environment, such as a temperature-controlled room, to minimize external factors that could influence the melting point.
By following these actions, the scientist can increase the accuracy of the results and obtain reliable data for determining the melting point of the new substance.
