The characteristic of an Iodine which has a much higher vapour pressure could be held responsible of its spontaneous sublimation. Even though is has a greater intermolecular force (Van der Waals), it would still have the tendency to change the phase into a gaseous state when the pressure reaches 1 atm.
Answer:
The correct answer will be option-Evaluating it with experimentation and argument
Explanation:
Scientific knowledge expands and flourishes every day due to the developments of the new techniques and research advancements.
The research process is based on the scientific method which involves the generation of hypothesis and performing the experiments to prove it.
The formation of the hypothesis is the important component of the method but the repetition of the experiment is the key component of the scientific world as the knowledge in science is based on the repetition of the experiments and argumentation during communication of the results.
Thus, the selected option is the correct answer.
Answer:
5.04%
Explanation:
The accepted value of density = 3.427 g/ml
The calculated value of density = 3.600 g/ml
We need to find Ally's percentage error on her density. The error in any value is given by :
So, the required error is 5.04%.
