Tempered safety glass has which of the following features?

Tempered safety glass possesses a variety of unique features that greatly enhance its strength and safety profile, making it an essential material in the automotive industry and other applications. One of the defining characteristics of tempered glass is that it undergoes a special heating and rapid cooling process, which significantly increases its strength compared to regular glass of the same thickness. This process not only enhances its structural integrity but also ensures that, when shattered, tempered glass breaks into small, blunt pieces, minimizing the risk of injury.

The combination of these attributes means that tempered glass is indeed 5-10 times stronger than its non-tempered counterpart. This strength allows it to withstand greater impact and temperature changes, making it an ideal choice for vehicle windows and windshields which are often subjected to varying conditions.

Since all the listed characteristics describe important aspects of tempered glass—its ability to disintegrate into dull-edged pebbles, its enhanced strength compared to non-tempered glass, and the specialized heating and cooling process used in its production—selecting the option that states all responses are correct is justified. Each feature contributes to the overall understanding of why tempered glass is valued in safety applications, especially in automobiles.
