How did Robert Millikan's oil drop experiment change scientists' view of the atom?
Robert Millikan's oil drop experiment, conducted in 1909, provided the first accurate measurement of the charge of the electron. By observing the behavior of tiny oil droplets in an electric field, Millikan demonstrated that electric charge is quantized, meaning it exists in discrete amounts. This finding reinforced the idea of subatomic particles and contributed to the understanding of atomic structure, leading scientists to recognize that atoms are composed of smaller charged particles. Millikan's work helped shift the scientific perspective toward a more nuanced model of the atom, incorporating the existence of electrons and their quantized nature.
What else can I help you with?
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 is the name for the condition that is manipulated by scientists?
The condition that is manipulated by scientists in an experiment is called the independent variable. It is the variable that researchers intentionally change to observe its effect on the dependent variable.
How joule Thomson experiment lead to coefficient?
The Joule Thomson experiment involves measuring the change in temperature of a gas as it expands through a throttle valve. The Joule Thomson coefficient is defined as the temperature change per unit pressure drop. By quantifying the temperature change in relation to the pressure drop, scientists can determine the Joule Thomson coefficient for a specific gas under certain conditions.
What is the variable in an experiment?
The variable in an experiment is the element that is being tested or measured. It is the factor that can change or be manipulated to observe its effect on the outcome of the experiment. There are independent variables, which are manipulated by the researcher, and dependent variables, which are what is being measured.
How did milikans oil drop experiment change scientists view of the atom?
Millikan's oil drop experiment, conducted in 1909, provided the first precise measurement of the elementary electric charge. By observing the behavior of tiny oil droplets in an electric field, Millikan demonstrated that electric charge is quantized, existing in discrete units. This experiment bolstered the atomic theory by confirming that atoms contain charged particles, specifically electrons, and helped to solidify the understanding of atomic structure, leading to advancements in quantum physics. Consequently, it shifted scientists' views by establishing that atoms are not indivisible but composed of smaller charged components.
How did Millikans experiment change your view on atoms?
Millikan measured the first the electrical charge of an electron.
What is the factor that scientists change in controlled experiment is the?
the anwer is a variable( the thng that will change over time in the experiment
What occurs when the expectation of a scientist change how the result of an experiment are viewed?
Bias occurs when scientists' expectations change how the results of an experiment are viewed.
What occur when the expectation of a scientist change how the results of an experiment are viewed?
Bias occurs when scientists' expectations change how the results of an experiment are viewed.
Do scientists change the independent variable or dependent variable in a experiment?
yes
Why do facts in science change?
Facts in science change because scientists do experiment's and find out new things.
What is the name of the factor that scientists change when designing an experiment?
The name of the factor that scientists change in an experiment is called the independent variable. It is the variable that is deliberately manipulated or adjusted to observe its effect on the dependent variable, which is the outcome being measured.
Who discovered change of electron by oil droplet experiment?
Robert Millikan discovered the change of electron using the oil drop experiment in 1909. He was able to measure the charge of an electron accurately using this method.
Why is it important to use constant in an experiments?
so scientists can compare result
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 five skills do scientists use in scientific inquiry?
What is the factor in an experiment that you measure and that may change because of what you are testing
Why might scientists repeat a study under slightly different circumstances than the original?
The original conditions may not have been conducent to good results, for example, scientists testing heat transfer and didn't use a completely closed environment in their experiment may have the conditions changed by other scientists who are peer-reviewing the experiment. They may also change it to see how the change alters the results
