The precaution to be taken while measuring the temperature of a liquid in a beaker is applying proper heat balance and taking all the required precautions.
- A beaker with an open top contains a sample of liquid. It exposes this sample to light.
- That liquid absorbs the light energy, turning it into heat energy. As a result, the liquid becomes warmer and evaporation is accelerated. As a result, there is less liquid in the beaker.
- Since it is well known that the surface temperature of a liquid, along with air movement above the liquid surface, is one of the dominant factors affecting evaporation, I want to measure the evaporation rate as a function of surface temperature.
- This can be done by applying a heat balance.

To start this test, you need to identify the variables it presents. As you may already know, there are independent and dependent variables. Independent variables are those that act on a factor, influencing it to generate a result. In the case of this experiment, the independent variable is the completion of the homework. The dependent variable, in turn, is the factor that receives the influence of the independent variable, in this experiment this variable is the final grade you received in the course.
After that you must select a number of students, give them their homework and ask each student to complete a percentage of that amount. An example of this could be that you select 11 students and ask the first to complete 0% of the homework, the second student must complete 10%, the third 20% and so on, and the 11th student must complete 100% of the homework.
after that, note what was the final grade that each student received in the course and make a graph to show the results.
The y-axis of the graph must represent the dependent variable, while the x-axis must represent the independent variable. This way you will show the exact relationship between completing homework and the final grade of the course.

Answer:
The position of an equilibrium always shifts in such a direction as to relieve a stress applied to the system -Le Chåtelier's principle
A molecule that donates a proton when it encounters a proton acceptor.- Bronsted-Lowry acid
Occurs when a reaction involving an acid and its conjugate base is combined with a second reaction involving a base and its conjugate acid.- Neutralization
It ionizes completely when dissolved in water.- Strong acid
The shift in the position of equilibrium caused by the addition of a participating ion.- Common ion effect
It only partially ionizes when dissolved in water.- Weak electrolyte
It is capable of acting as either an acid or a base depending upon the solute- Amphoteric solvent
The act of self-ionization of a solvent to produce both a conjugate acid and a conjugate base.- Auto-protolysis
A chemical species that bears both positive and negative charges.- Zwitterion
Explanation:
In the answer box we have various chemical terminologies and their definitions. In answering the question, you must carefully read through each definition, then check what option best matches that definition from the options provided.
Each definition applies only to one terminology as you can see in the answer above.
