Question

Suppose that during the experiment, a student forgot to put the lid on the calorimeter. What is the most likely error and reason?
A). Temperature readings will be too high because heat will be absorbed by the air.

B). Temperature readings will be too high because the lidless coffee cups will give off heat.

C). Temperature readings will be too low because heat will be absorbed by the air.

D). The temperature readings will be too low because the lidless coffee cup will absorb more heat.

Answer 2

Answer: Option (C) is the correct answer.

Explanation:

A calorimeter is a device with the help of which we can measure the temperature of a chemical reaction.

So, when the student forgets to put lid on calorimeter then heat from the reaction mixture is going into the surroundings. As a result, there will be a decrease in reading of the calorimeter due to the loss of heat from the reaction mixture.

Thus, we can conclude that the most likely error and reason for the given situation is temperature readings will be too low because heat will be absorbed by the air.
