<span>The usual answer (and correct) is to improve on the insulation, for example by covering the calorimeter, and using two cups, one inside the other.
Further improvements can be made
1) carrying out the experiment over as short a period of time as possible. reason; any calorimeter will loose heat, but the shorter the time allowed, the less heat will be lost.
2) Use a larger calorimeter, with greater volume of solution. reason; the greater the solvent mass requires more energy to obtain the same change in temperature. You get a smaller temp change for the same reaction, so less losses to the surroundings.
3) calibrate your calorimeter heat the same volume of pure water to a similar temperature as that which the reaction produces. Then determine the rate of heat loss over a period of time, say take temp every minute for 30 minutes, and plot a graph. This will give you a calibration curve that you can use to apply a correction for your calorimeter.</span>
Answer:
Two possible consequences that an employee does not meet all the requirements in an employment contract are, on the one hand, the eventual loss of the job and, on the other, a less possible readjustment of tasks for the employee. Thus, if this does not meet the requirements of the company, it is most likely to dispense with its services through firing him, either (if it is an employee with a certain history in the company, or has characteristics that make it necessary for it) modifying their job responsibilities.
Answer:
The advantages of the multi-stage fitness test and the direct VO2 measurement are that it is the most accurate testing, but it requires hard work.
Answer:
engaging in positive peer pressure
Explanation:
they are encouraging her to do better by putting themselves in a spot as to do better with her. peer pressure because she will be influenced by their actions and positive because they are doing it in hopes that she will improve.
