Answer:
A
Explanation:
PRECISION AND ACCURACY ARE TERMS THAT ARE USED TO INDICATE THE QUALITY OF A GIVEN SET OF STATISTICAL OBSERVATIONS.
WHILE PRECISION TALKS ABOUT THE LEVEL OF AGREEMENT AMONGST THE SAME SET OF DATA OBSERVATIONS, ACCURACY TALKS ABOUT HOW FAR OR HOW CLOSE THE TRUE VALUE IS TO THE CALCULATED VALUE. TAKING AN AVERAGE OF ALL THE VALUES, IT STANDS AT 4.735 WHICH IS QUITE CLOSE TO THE TRUE VALUE OF 4.75
NOW, LOOKING AT THE SPREAD OF THE VALUES IN THE OBSERVATION, WE CAN SEE THAT THESE VALUES ARE QUITE NOT CLOSE TO EACH OTHER. HENCE, WE CAN CONCLUDE THAT ALTHOUGH HIS OBSERVATIONS ARE QUITE QUITE ACCURATE BASED ON THE OVERALL AVERAGE, WE CAN CONFIDENTLY POSIT THAT HIS VALUES HAVE A LOW LEVEL OF PRECISION
After reading all the options represented above, I nodiced that four of them are connected to chemistry, and the only activity that was performed by a chemist is primarily based on an understanding of physics is the third option from the box. C)predicting the boiling point of a liquid, given its pressure
while sdudying physics you often come across with such tasks where you need to find the boiling point by using the capability of reservoir with water and its size etc.
Answer:
Pressure is inversely related to volume.
Temperature is inversely related to moles.
Volume is inversely related to pressure.
Moles are inversely related to temperature.
Answer:
D. chemical alters the atomic structure of a substance, while physical does not
hope this helps!
Answer: Lithium Fluoride
Explanation: Let’s see,,,
1. Obviously not hydrogen or carbon dioxide because they’re gas at room temp.
2. Lithium Fluoride is an ionic compound which means they have higher intermolecular forces and require more energy to break them, so it probably has a higher boiling point.
