Technically yes but no because you have to fill the 3s orbital before the 5s orbital.
Well research shows that it's not technically a chemical change. you need to find out whether you are looking for silica or to use glass changes on a molecular level when heated or if it's melted into another form (physical change). It appears that to make glass you simply melt silica into the resulting product, which is glass. there is not a chemical change or molecular change. Therefore, <u>making glass<em /></u> from sand is a <u>physical</u>, not a chemical change.
4) definite shape and definite volume
<span>During freezing heat will be released. Normally we wont think like that ,but the reality is during freezing the heat get released. the liquid water will have more energy than the frozen water .so during this transition the energy of the water get released as the latent heat. Basically when we need to reduce the temperature ie. freezing a substance, the heat already absorbed in the substance should be released out of the substance.</span>
