Substance 1 is solid
Reason: It is brittle. Being brittle means it is easy to break, so it must be solid.
Substance 2 Is liquid
Reason: The room temperature is about 25 degrees Celsius which is above its melting point, and since it boils at 150 degrees, it means at room temperature it will still be in liquid state.
Substance 3 is solid
Reason: Its melting point is much higher than the room temperature
Reason: It is brittle. Being brittle means it is easy to break, so it must be solid.
Substance 2 Is liquid
