Explain why higher temperature in a substance does not mean the substance has more thermal energy?
Answers
Answer:
Temperature is the average kinetic energy of particles of an object. Warmer objects have faster particles and higher temperatures.
Explanation:
If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature is measured with a thermometer.

Answers
Answer:
Mixture
Explanation:
When a prospector scoops up part of the stream bed, the pan contains stream sediments.
The term that best describes what is in his pan when he scoops up part of the stream bed is the mixture. Thus, the correct option for this question is A.
What is a Stream bed?A stream bed may be defined as the strait extremity of a stream or river through which the physical confine of the normal water flow. It is a type of channel significantly occupied by a stream.
According to the context of this question, when a prospector scoops up part of the stream bed, the pan contains stream sediments, which implies that the mixture contains stream sediments or contamination.
Therefore, the mixture is the term that best describes what is in his pan when he scoops up part of the stream bed. Thus, the correct option for this question is A.

Answers
Answer[tex]__________ is a set of _____ or combination of __________ alleles responsible for an _________ of a trait.[/tex]:
Explanation:
The bonds are formed by the valence electron of the atom. The covalent bonds show poor thermal conductivity and are hard and brittle substances. Thus, options 1. c and e, 2. b and f, 3. a and d are correct.
What are chemical bonds?Chemical bonds are the linkages formed between the atoms of the same or different element by transfer, sharing, and moving electrons of the valence shell of the orbital.
The covalent bonds are formed by sharing the valence electron with the atoms that look hard and brittle and are poor thermal conductors. Thus, options c and e are correct.
The metallic bonds, on the other hand, are formed by the free movement of the electrons in the structures that are ductile and are represented by the electron sea model. Thus, options b and f are correct.
Lastly, the ionic bonds are created by the transfer of the valence electron from one to another atom. They form crystalline structures and molecular compounds with cations and anions in them. Thus, options a and d are correct.

What geometric shape is the carbon dioxide molecule? The Lewis structure for CO2 contains two double bonds.
Answers
Explaination: The central atom of a carbon dioxide molecule is carbon. Carbon is tetravalent which just means it has 4 valence electrons. Because the valence shell isn’t full, the carbon atom can bond with other atoms creating a total of 4 bonds. This then allows the carbon to double bond with 2 oxygen atoms. Now, the atoms in the CO2 molecule Don’t share the electrons evenly because of atomic number or proton count. Because oxygen has an atomic number of 6, carbon has an atomic number of 4, and opposites attract (referring to the positivity of the nucleus and the negativity of the shared electrons), the oxygen atoms will have a slightly negative charge (-) and the oxygen will have a slightly positive charge (+ ). Therefore, the slightly negative oxygen atoms repel creating that linear shape.
