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? benzene water butane nitrogen

Benzene

Explanation:

You have to find the freezing point for each of these (make sure they're in Celsius). You might want to double check these but:

Benzene: 5.5

Water: 0

Butane: -138

Nitrogen: -210

Benzene!

Explanation:

It freezes at 5.5 C, meaning that as the container is gradually cooled, it will freeze first.

Hope this helps!!

b.

the accuracy of the data.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
