The table below shows the freezing points of four substances. ( substance freezing point (°c) benzene 5.5 water 0 butane –138 nitrogen –210 ) the substances are placed in separate containers at room temperature, and each container is gradually cooled. which of these substances will solidify before the temperature reaches 0°c? 1.benzene 2.water 3.butane 4.nitrogen

The correct answer is Option 1.

Explanation:

Freezing point is defined as the point where liquids starts to solidify. It is temperature at which liquid and solid states of a substance are present in equilibrium at the atmospheric pressure.

Freezing point of given substances are:

Benzene = 5.5°C

Water = 0°C

Butane = -138°C

Nitrogen = -210°C

The substance which solidifies before the temperature of the container reaches 0°C will be benzene because the freezing point of this substance is high and will solidify first.

Hence, the correct answer is Option 1.
