Explanation:
No of molecules=0.500×6.023×10²³=3.011×10²³ molecules
Answer: Matter is heated, and its particles spread out more
Explanation:
Thermal expansion occurs when there's an expansion of an object or material or when an object becomes bigger because of a rise in its temperature. This brings about the faster movement of the heated molecules and the atoms spreading out.
Therefore, the cause and effect of thermal expansion will be that when matter is heated, and its particles spread out more.
True. Covalent bonds involve sharing electrons to create a full valence shell.
