3 / 10

The melting temperature of Silicon is about 1400 °C. Based on your analysis, is the gasket safe from melting?

Yes, it is safe in both cases

It is safe only in System A (“Warm Day”) but not in System B (“Cold Day”)

It is safe only in System B (“Cold Day”) but not in System A (“Warm Day”)

No, it is not safe in both cases
