N + n+I + n+2 + n+3 + n+4 + n+5 + n+6 = 224
7n+2I = 224
7n = 2O3
n = 29
29 has the least value in this list.

Heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from one atom to another. Conduction is the most significant means of heat transfer within a solid or between solid objects in thermal contact.
Answer:
Safety precautions in the heat transfer laboratory depend on the equipment that you will use.
Explanation:
The safety measures or precautions that an experimenter needs to bear in mind depends on the types of equipment he/she's using in experimenting. But, there are general precautions to consider.
There are three different ways to transfer heat, including convection, conduction, and radiation. <em><u>Convection</u></em><u> </u>pertains to the heat transfer between liquid or gas molecules moving circularly. Through that, their temperature and density are both affected. <em><u>Conduction</u></em><em> </em>and radiation are polarities. The heat transfer happened when two objects touched one another in conduction. On the other hand, <em><u>radiation</u></em> occurs when two objects do not touch each other.
Generally, precautions in performing these three experiments include the following:
- Careful handling of glassware to avoid cracking or breaking it.
- Avoid spilling the liquid or any content of the glassware.
- Do not touch any hot object.
- Use a hot pad to transfer hot objects from different places.
