How can a researcher ensure that water being used for an experiment will vaporize at a point lower than normal temperature?
By decreasing pressure in the container (: Plato is easy !
To ensure that an experiment is testing only one variable scientists often run a?
Control Experiment
How can you ensure that a tympanic temperature is accurate?
rectal
Something that causes changes in an experiment?
The factors that can influence the course of a reaction are known as variables and or sources of error. Experiments and testing seek to control these variables, errors and account for them to ensure quality and safety of their results.
What causes high exhaust temperature in marine engine?
Engine overload, insufficient scavenge air (ensure blower suction filters are not clogged), also ensure no air leakage between the blower and scavenger, expanded injection nozzles, damaged or worn valves or valve seat.

How can a researcher ensure that water being used for an experiment will vaporize at a point lower than normal?
Conduct the experiment is a pressure vessel where the pressure is maintained at a point lower than normal.
What is Thompson experiment?
It is an experiment in which the Joule-Thomson coefficient is measured. Basically, you are expanding a gas under adiabatic conditions to ensure constant enthalpy and you will notice that there will be a temperature change (most likely cooling).
How will you ensure safety while performing experiments?

Why do you need to calculate standard deviation and relative error?
to ensure your experiment is precise and to prevent error to happen during experiment
What is the controlled experiment in a science experiment?
The control in a science experiment is the same thing as a constant. It is something that you keep the same the entire experiment. For example if you were testing how various locations affect temperature your constants would be the thermometer you used and the time for measuring the temperature. If you don't have a constant than your experiment results won't be accurate.

What are constants in an experiment?
Constants are the things that are kept the same each time one of the trials in the experiment is repeated. For example, constants could include the amount of water used, the brand of effervescent tablet used, the type of water used, and the fact that the water was not stirred. As many outside factors as possible should be kept constant in an experiment so that the researcher can be sure that any changes that occur do so because of the independent variable.
Who is responsible to ensure that safety procedures are followed when conducting an experiment?
When conducting an experiment in a laboratory environment, the person conducting the experiment and the Instructor or Principle Investigator are responsible for ensuring that appropriate safety procedures are followed.
What is the control condition?
While conducting an experiment, it is important to have a experimental control. Suppose you are conducting an experiment to determine what factors affect the rate of evaporation of water. If you want to determine if presence of wind affects evaporation, you can take two containers of water and place one in a windy place and the other in a place with no wind. However all other factors should be identical like surface area of containers, surrounding temperature, liquid quantity and temperature etc. Hence, the need for a controlled experiment is to eliminate bias and to ensure that the data is valid.
What do scientists write after they summarize their experiment and results?
they do finally arrive at Theory w to ensure no bias existed in the original experiment hich later lead to law/principle
