What scientific test can you use to work out the age of an object?
scientists can determine the age of somthing by finding out how much carbin 14 there is left in the sample. the reason fro using carbon 14 is because it has a very predictable half life of 5730(plus or minus 40) years. half life is the decay rate of certain materials. by knowing the begging amount of carbon 14 present in the sample they can determine by the amount left how old it is.this is a pretty easy subject to look up if you have any pther questions.
Why is a conical cap provided to a pycnometer?
A conical cap is provided to a pscnometer to determine the volume of the test sample.
Which of these is not used to determine the age of an object?
magnetometer
For this statement which could be a hidden variable?
Type your answer hereWhich people were selected for the sample.. Age
What happens when carbonic acid is mixed with feldspar?
Feldspar, a major constituent of most igneous rocks, reacts with carbonic acid to produce residual clay minerals plus dissolved ions of metals (potassium, sodium or calcium, depending on the type of feldspar). Here, for example, is the reaction by which potassium feldspar is converted to kaolinite, a clay mineral: 4KAlSi3O8 + 4H2CO3 + 2H2O → Al4Si4O10(OH)8 + 4K+ + 4HCO3- + 8SiO2 feldspar + carbonic acid + water → kaolinite + dissolved potassium and bicarbonate ions + dissolved silica Similar reactions affect sodium feldspar and calcium feldspar.
What is used to determine the absolute age of a sample?
Carbon dating. Google it
Can the age and sex be determine by hair sample?
Usually, yes, you can get a rough guesstimate of a persons age from their hair sample, you can usually tell male or female also.
What type is Sample B on Mineral Identification on Gizmo's?
Sample B on the Mineral Identification Gizmo is calcite.
What is the use of measuring the activity of a radioactive isotope in a sample to determine its age?
Measuring the activity of a radioactive isotope in a sample allows scientists to determine the amount of time that has passed since the sample was formed. By comparing the current activity of the isotope to its original activity, scientists can calculate the age of the sample, a technique commonly used in radiometric dating to estimate the age of rocks, fossils, and archaeological artifacts.
How old is a live oak tree that is 17 feet in diameter?
A core sample would have to be taken to determine its age
What is the maximum amount of plagioclase feldspar possible in a sample of granite?
65%. Any more, and it is not considered granite.
How do scientists use half lives to determine age?
Scientists use the concept of half-life to determine the age of a sample by measuring the remaining amount of a radioactive isotope in the sample. By knowing the half-life of the isotope and the initial amount present, they can calculate how much time has passed since the sample was formed. This method is commonly used in radiometric dating of rocks, fossils, and other materials.
Do isotopes determine the size or age of a rock?
Isotopes can be used to determine the age of a rock through radiometric dating, but they do not determine the size of the rock. By measuring the ratio of parent and daughter isotopes in a rock sample, scientists can calculate its age based on the rate of radioactive decay.
Can you tell age from a blood sample?
Yes. In a similar way that scientists can use carbon dating to determine the age of fossils, a new method allows an individuals age to be determined from their blood. X-ray florescent spectroscopy allows the bloods plasma to be analyzed with enough precision to determine age within the year.
What is carbon-14 dating and how is it used to determine the age of organic materials?
Carbon-14 dating is a method used to determine the age of organic materials by measuring the amount of carbon-14 remaining in a sample. Carbon-14 is a radioactive isotope that decays over time, so by comparing the amount of carbon-14 in a sample to the amount in living organisms, scientists can calculate the age of the material.
How does carbon dating work to determine the age of archaeological artifacts?
Carbon dating works by measuring the amount of radioactive carbon-14 in a sample. Carbon-14 is a radioactive isotope that decays at a known rate over time. By comparing the amount of carbon-14 in a sample to the amount in living organisms, scientists can determine the age of the artifact.
How do you determine an adequate sample size?
A sample size is needed whenever you conduct an experiment. How you determine an adequate sample size depends on the scope of what you're testing, such as medications.
