The correct answer would be the first option. Material A having a smaller latent heat of fusion would mean that it will take only less energy to phase change into the liquid phase. Latent of heat of fusion is the amount of energy needed of a substance to phase change from solid to liquid or liquid to solid.
Answer:
- <em>The measurements taken by </em><em><u>Jay</u></em><em> are least likely to contain random errors.</em>
Explanation:
All experimental measures are subject to errors.
Even when the colorimeter is properly calibrated and correctly used, there are random errors.
Random errors are are due to fortuitous factors, such as minor oversight by the observer or small changes of the conditions under which the measurements are made.
You can minimize the random errors by increasing the number of measurements, because the random errors tend to happen in any direction; some measures will be greater and other will be less than the true value.
Chance will make that errors in on direction cancel with errors in the opposed direction, making the average the best measure.
Thus, <em>Jay</em>, by <em>repeating the experiment five times and taking the average measurement</em>, is making that<em> his measurements are</em> <em>least likely to contain random errors.</em>
Answer:
temperature, refractive index, density, and hardness of an object
Explanation:
it is a bulk property, meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system
Answer:
chemical energy is the energy of a chemical substance that is stored in the bonds of chemical compounds and is released when they undergo a chemical reaction and transform into another substance
Explanation:
This reaction between an acid and a base is called a neutralization reaction and the products of this reaction are salt and water..The base in this case is sodium hydroxide, acid is hydrochloric acid and the salt formed id sodium chloride.
