A teacher covered the scale of a mercury thermometer to test the ability of the students to measure the boilling point of umknown liquid which of the following represents the boiling point of that liquid knowing that it is boiling point is lower than that of water
75.5c
84.5c
104.5c
105.5c
It is not possible to determine the boiling point of the unknown liquid based solely on the options provided.
In this case, we can determine the boiling point of the unknown liquid based on the given information that its boiling point is lower than that of water.
The boiling point of water is 100°C. So, we need to select the option that represents a boiling point lower than 100°C.
Among the given choices, the only option that represents a boiling point lower than 100°C is 75.5°C. Therefore, 75.5°C is the boiling point of the unknown liquid.
