Answer 8

Solid

Question 9

Answer 9

Energy

Question 10

What is the difference between accuracy and precision? Short answer

Answer 10

Accuracy-is the measurement of how close the value is to the actual value
Precision- is the measurement of how close the values are in relation to each other

Question 11

What is the difference between a molecule and a mixture?

Answer 11

Molecule- is a chemical combination of two or more atoms

Mixture- is a physical combination of two or more elements or compounds

Question 12

Compare and contrast alpha decay and beta decay?

Answer 12

Alpha decay occurs when a nucleus emits a high-energy particle of two protons and two neutrons, whereas beta decay occurs when a neutron’s down quark changes into an up quark, changing the neutron into a proton and forcing the emission of an electron.
