Question

glass can be obtained from sand but sand can not be obtained from sand give reasons​

Answer 1

Explanation:

Explanation: To make glass, the sand – together with limestone and soda – is heated to 1400°C. Unlike opaque materials like metals, the electrons in the resulting compound don't have much freedom within its crystalline structure, and thus are not very effective at absorbing light energy

Answer 2

Answer:

Answer: Believe it or not, glass is made from liquid sand. You can make glass by heating ordinary sand (which is mostly made of silicon dioxide) until it melts and turns into a liquid. You won't find that happening on your local beach: sand melts at the incredibly high temperature of 1700°C (3090°F).
