Final answer:
The statement is true; hot glassware should always be handled with clamps or tongs to prevent burns and ensure laboratory safety. Following safety guidelines and using appropriate protective equipment is crucial in a laboratory setting.
Step-by-step explanation:
The statement 'Hot Glassware - handle with clamp or tongs' is true. When working in a laboratory setting, safety is paramount. Hot glassware must be handled using appropriate equipment like clamps or tongs to prevent burns. This is a fundamental safety practice to ensure the wellbeing of individuals in the lab.
Multiple safety warnings, such as the dangers of burning oneself with hot glassware like beakers or spoons, emphasize the importance of following proper safety protocols.
It is also crucial to pay attention to other safety guidelines, such as wearing gloves, goggles, and safety aprons when required, not eating or drinking in the lab, and being cautious with chemicals and Bunsen burners. For example, a common experiment involved the phase change and latent heat, where handling ice cubes with salt could show changes in melting due to the added salt.
Understanding the thermal properties of various materials, like glass and metals, and the correct way to handle them is key to preventing accidents and ensuring a safe laboratory environment.
