Will absorb heat
Will not absorb heat
उत्तर
Will not absorb heat
Explanation:
- Glass is a poor heat conductor, but it absorbs and releases heat slowly.
- Thin glass can heat up and cool down quickly, causing it to break, while thicker glass absorbs heat more slowly.
- Certain types of glass, such as tempered glass or Pyrex, can tolerate heat more and distribute it more evenly.
