How do you Summarize the properties (temperature salinity density) you would expect to find at different depths of the ocean?
In general, as you descend deeper into the ocean: temperature decreases, salinity tends to increase due to evaporation and freezing processes, and density rises due to the combined effects of temperature and salinity variations. These properties play a crucial role in shaping the ocean's circulation patterns and influencing marine life distribution.
How can the students compare and contrast earth's section?
Students can compare and contrast Earth's sections by examining differences and similarities in composition, characteristics, and processes. For example, they could compare the solid crust to the liquid outer core in terms of state of matter and behavior. By exploring variations in temperature, pressure, and density in different sections, students can gain a deeper understanding of Earth's structure.
What is the average temperature in a classroom?
"Room temperature" usually refers to 21°C, which is about 70°F, and this is the scientific standard. It may also refer less specifically to whatever the current temperature is in a given context, as in food "served at room temperature"--neither heated nor chilled.
What is the reaction of silver nitrate and calcium chloride?
Got this from chemtutor.com - better answer BALANCING IONIC EQUATIONS WITH POLYATOMIC IONS Silver nitrate and calcium chloride solutions combined produce a precipitate of silver chloride and leave a solution of calcium nitrate. This time we have ionic compounds in the reaction. Until you are sure of the compounds, you might want to write the ionic materials as the ions, as demonstrated here. _ Ag+(NO3)- + _ Ca2+Cl-2 _ Ag+Cl- + _ Ca2+ (NO3) -2 Notice that from one side to the other there is no change in the nitrate ion. In this case you can count the nitrate ion as a whole rather than splitting it up into nitrogen and oxygen. Your thoughts might go this way: How many silvers on the right? One. How many silvers on the left? One. They are the same. How many nitrates on the left? One. How many nitrates on the left? One. How many nitrates on the right? Two. We need to put a coefficient of two in front of the silver nitrate. 2 AgNO3 + _ CaCl2 _ AgCl + _ Ca (NO3)2 This changes the balance of silvers, so we have to put a two in front of the silver chloride. 2 AgNO3 + _ CaCl2 2 AgCl + _ Ca (NO3)2 Now let's check again. Two silvers on each side. Two nitrates on each side. One calcium on each side and two chlorides on both sides. The balanced reaction is: 2 AgNO3 + CaCl2 2 AgCl + Ca (NO3)2 Hope this will come handy! =] UNBALANCED: AgNO3 + CaCO2 ---> AgCO + Ca(NO3)2 BALANCED: 2AgNO3 + CaCO2 ---> 2AgCO + Ca(NO3)2 >> as a note to the previous editor... that is not calcium chloride in the mix, it is instead calcium carbonate... students take note...<<
What is the main idea of writing a science project when the answer is which one freezes the fastest water salt water sugar or water its self?
The main idea of writing a science project to determine which solution freezes the fastest (plain water, salt water, sugar water) is to investigate the impact of different solutes on the freezing point of water. By conducting experiments and analyzing data, students can learn about the concept of freezing point depression and how solutes affect the physical properties of a solution.
Purpose of freezing salt and water?
It makes an interesting experiment for students. It gives them something to ponder over.
The science students gather information about feasibility of solution options to lower the number of students in the hall.?
soution design and evaluation
Is this sentence correct you hope that this will be a long lasting solution to recruiting prospective students from Nigeria to study at Amity University Mauritius?

What unusual thing happens which causes school to be canceled?
The freezing winter. It was the coldest winter since 1885, and the temperature was around 16 degrees Fahrenheit.
Some slogans for students on environment?
green revolution is the best solution to arrest the pollution
According to the stgudents, which solute should they use in their cold pack A. ammonium chloride B. sodium chloride C. calcium chloride D. sodium acetate?
The students should use option D, sodium acetate, in their cold pack. Sodium acetate undergoes an endothermic reaction when dissolved in water, absorbing heat from the surroundings and creating a cooling effect. This makes it an ideal choice for cold packs as it helps maintain a low temperature for longer periods of time compared to the other solutes listed.
Should you go to school with a temperature of 98.4?
Well you can but you have to be careful with other students
What is KCI formula?
The KCI formula stands for Knowledge, Confidence, and Interest. It is a framework used in education to assess students' understanding of a topic by evaluating their knowledge of the subject, confidence in applying that knowledge, and interest or engagement in the topic.
What causes breakdown in communication between teachers and students?
The breakdown in communication between teachers and students is disrespect. The solution starts with the teachers learning how to behave, instead of reacting to a situation, Behavioral skills are important to teachers and students
Which minerals helps keeps schools open during snowy and icy weather by melting ice?

There are 270 sixth grade students abd 45 chaperobes going on a field trip how many students will be with each chaperone if the groups are divided equally?
You would divide 270 by 45 and the solution would be 6 students with each chaperon.
