Final answer:
Hot glass and cold glass do not look the same. Glass is a solid at room temperature and does not flow like a liquid.
Step-by-step explanation:
False. Hot glass and cold glass may appear the same, but they have different thermal properties. Glass is considered a solid at room temperature and does not flow like a liquid. The idea that old windows are thicker at the bottom is a myth with no credible evidence. The thicker part of the glass is usually placed at the bottom for structural support.
