Can temperature and pressure change the neutralization of a solvent?
Unless the solute is frozen , the temperature and pressure in a room should not change the neutralization of a solute. This is because the solvent and all other aspects of the experiment would be equally affected, and the solute's temperature would balance itself out.
Which is a value that should remain constant for all samples in this experiment?
It could be many things such as temperature or pressure.
Does the final temperature from the experiment equal to the final temperature from the calculation?
It should but it probably will not because of: experimental error measurement error calibration error (zero error)
What can scientists do if the results of an experiment do not support a hypotheses?
They should try again. Then check very carefully and see if they did the experiment correctly. They may have to change their hypothesis.
What does it mean to identify and control variables?
Variable means 'can change'. If a science experiment is to produce clear information, we should change only one thing at a time. The condition we change is called the independent variable. For instance we might decide to change the temperature of hot water and see how that affects how long potatoes take to cook in it. Temperature is the independent variable, and cooking time is the dependent variable. If we want to be sure that changing the temperature is the only thing affecting the results, we must ensure nothing else changes from run to run. We must keep the size of the potatoes, their variety, the amount of salt in the water and the cooking vessel the same. These are the controls, or control variables.The controls are the substance or material or measurement in the experiment that stays constant and doesn't change while the variable is the object compared to the control which varies in results and can change through out the course of the experiment.
When the biologist designs her experiment what should be the manipulated variable of the experiment?
temperature

What temperature is important to record in a freezing point determination experiment?
if you could only record a single temperature reading in a freezing point determination experiment, which temperature should you record
When the chemist designs his experiment what should be the only independent variable?
temperature
How many variables should you have to change in an experiment?
2
How many variables should you change at a time in an experiment?
8
What change is observe when a leave was boiled in warm water in a experiment?
The grammer is wrong here...should be "what change is observed when a leaf was boiled in warm water in an experiment".
What is conclusion for a lava lamp experiment?
The conclusion for a lava lamp experiment depends on the thesis. If the thesis talks about the temperature for example the conclusion should reflect that.
How many variables should change in a scientific experiment?
It depends what kind of experiment you do. For some you just need one. For others you may change two variables. In most cases you only change one
Which is a value that should remain constant for all samples in this experiment?
It could be many things such as temperature or pressure.
A chemist hypothesizes that mercury oxide will undergo a decomposition reaction if it reaches a certain temperature When the chemist designs his experiment what should be the only independen?
temperature
What is the difference between static and dynamic variables?
Static variables (should) remain the same e.g. temperature of a water bath, k constant of a particular spring. Dynamic variables change as the experiment progresses e.g. air temperature and pressure, amount of natural light.
