Answer :
Final answer:
The appropriate tools for moving potentially hot objects in a laboratory include test tube tongs, crucible tongs, and hot hands. Items like evaporating dishes, wire gauze, ring stands, and hot plates are not used for moving hot objects directly. Always use proper safety equipment to prevent burns and injuries.
Explanation:
Moving Potentially Hot Objects in the Laboratory
When working in a chemistry laboratory, it is important to use appropriate tools for safely handling potentially hot objects. Here’s a guide on which items are appropriate for this purpose:
- Test Tube Tongs: Used for securely holding and moving hot test tubes.
- Hot Hands: These are protective gloves or sleeves designed specifically for handling hot objects.
- Crucible Tongs: Ideal for grasping crucibles, which can become extremely hot when heated.
Other items listed, such as an evaporating dish, wire gauze, ring stand, and hot plate are not typically used directly for moving hot objects, but they serve different functions in the laboratory:
- Evaporating dishes are used for heating liquids to promote evaporation but are not tools for gripping.
- Wire gauze is used to support glassware over a heat source.
- A ring stand is used for securing glassware and should not be used for direct handling.
- Hot plates are equipment for heating substances, not for moving them.
In conclusion, always use the appropriate tools such as test tube tongs, crucible tongs, and hot hands when dealing with hot items in the lab to ensure safety and prevent burns.
