<span>Eyes are sensitive to light and when light falls on them, they transmit electrical signals to the brain. The lens in the eye focuses light falling on it, on to the retina. Depeding on the amount of light and distance of objects from the eyes, the lens changes shape to allow focus on objects at varying distances and this is called accommodation.</span>
The substance is colder than it was because when particles move very quickly its either how or boiling so if its slow its cold and if it freezed the particles are well frozen
The correct answer is option (C) One student measures liquids for the experiment by holding the flask up at eye level. The other student measures liquids for the experiment while the flask sits on the table. Measuring liquids by holding the flask at eye level is the greatest amount of error in the experiment.
When liquid is being measured in a flask, the liquid shows a curve downwards which is called the meniscus. For measuring the transparent liquids, the lower meniscus touching the graduation of the should be considered and for measuring the colored liquids, the upper meniscus touching the graduation of the flask should be considered. When, the measurement is done by holding the flask at eye level there is always an error as it should be kept on a flat surface and measured by eyes directly leveling with the liquid. This gives a correct measurement which was done by the other student. Thus, one student measuring the liquid by holding the flask at eye level will have a wrong measurement and the other student measuring the liquid while the flask sits on the table gives the correct measurement and the results of the experiment will vary.
