As of 2018-19, only the grades 5 and 8 Statewide Science Assessment is still being administered. For information about those assessments, visit the Statewide Science Assessment page of the FDOE website. Practice materials for the Florida Standards Assessments (FSA) are available on the FSA Portal.
The FCAT 2.0 Sample Test and Answer Key Books were produced to prepare students to take the tests in mathematics (grades 3-8) and reading (grades 3-10). Sample Test and Answer Key Books for grades 5 and 8 science are available on the Statewide Science Assessment page. The Sample Question Books are designed to help students become familiar with FCAT 2.0 questions and to offer students practice answering questions in different formats. The Sample Answer Keys are designed to be used by teachers to explain to students the answers and solutions to the questions in the Sample Question Books and to identify which Next Generation Sunshine State Standards benchmark is being tested by the question.
Some people have been complaining about the differences between the solutions I have posted and the ones on mastering physics. Let me clarify something once again. These are the solutions to Physics by Knight, edition 1. NOT edition 2, which mastering physics now uses. As many of you know, book companies make most of their money by coming out with new editions of books that are simply the old book, but with mixed up problem numbers and a few new ones. That is why these answers do not always line up, also some of the mastering physics questions are conceptual, and are not always in the book so these conceptual ones will not always be on there either. Here is the correlation sheet that says which problems are which from edition to edition, hopefully this will help.
Well I decided that it would be extremely useful if I also provided the workbook solutions as they can be key to understanding the material and concepts at times. Here are the chapters that I currently have solutions for, they might be a little different than the current edition but I am fairly sure most of them are the same. Enjoy!
As far as some hints on the actual calculation ones I can tell you this; the hall voltage can be found on page 1023, and the science olympics as well as the lightbulb one can be found on page 956 (try calculating the E first and using it in the [A/(row)] E = I knowing that I is 100/120), also the second to last is just F = qvB (its going down the z-axis so its a negative sign) and the second part is just that multiplied by sin(45) for one and cos(45) for the other. Best of Luck!
Express the answer as two letters representing the endpoints of the line in order so that going from the first letter to the second letter would show a process of boiling. Be careful to put the letters in the correct order.
Part G: One of the most important points on a phase diagram is the triple point, where gas, liquid, and solid phases all can exist at once. What are the coordinates ( , ) of the triple point of ammonia in the diagram?
Part H: At one atmosphere of pressure and temperatures above , ammonia exists as a gas. For transportation, ammonia is stored as a liquid under its own vapor pressure. This means that the liquid and gas phases exist simultaneously. If a container of ammonia is transported in an temperature-controlled truck that is maintained at no greater than 330 , what maximum pressure must the sides of the container be able to withstand?
Explanation and Answer: This is a basic pV = nRT problem that consists of two phases. We first look at what we know and then see what we can solve for with our information that will help us get the necessary information. Knowing that the expansion is isothermal we know the temperature wont change so we can then solve for the finla pressure of the system with the following equation:
Now we are asked to find how long it will take for the water to completely freeze, to do this we will first need to value for the latent heat of fusion which is given to us in the chart as 333.7 j/g. So with this we can now find how much energy is required to completely freeze the water much like we did in the first one with the following equation however since there will be no temperature change we do not include (delta)t in our equation (notice latent heat is j/g not j/(g*K)).
Knowing the amount of time we are observing the object at we can just use the equation from the previous part coupled with the cooling power from earlier to find the amount of energy that would be removed from the ice once it was completely frozen. It is important to note that the hour time begins once we start cooling the water before it is even frozen so we must account for the time we previously calculated for when considering the hour of cooling.
Principles of Chemical Engineering (PCE) course is a core and highly important subject to study Chemical Engineering program that caters most fundamental concepts that bridge science to engineering. This study assess the effectiveness of portfolio workbook as a strategy to enhance student active learning in PCE. It was implemented for a full-semester and the student feedbacks on perceptions and implementation of the method was obtained after the course was completed. Results show that most participant agreed on the imposing mark on the workbook to enhance their study motivation. Vast majority of the students (>82%) admit that the workbook significantly helped them in mastering the subject, thus recommended the method for other subjects (>85%). The workbook as well as the method implementation can further be improved by providing short-answer as well as more intense scaffolding.
