II Answer the following 1. Metal Gallium is a liquid at room temperature. Its melting point is 29.76°C. The freezing point of water is O°C. How much warmer is the melting point of Gallium than the freezing point of water?
Answers
Correct option is
B
liquid state
Gallium melts at room temperature and has one of the largest liquid ranges of any metal. The melting point of gallium is used as a temperature reference point. At room temperature, gallium metal is unreactive towards air and water due to formation of a passive protective oxide layer. It melts at 29.76
∘
C (slightly above the room temperature). It is used as an agent to make alloys and is also useful in semicounductors.
