It is b because I need to answer my first question
Pairs of electrons are shared between two nonmetal atoms
hope this helps (:
Answer:
a) 
and 
b) 
and 
c) 
and 
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like 
, 
and 
These units of temperature are inter convertible.
a) 68°F (a pleasant spring day) to °C and K.
Converting this unit of temperature into and by using conversion factor:
b) 164°C (the boiling point of methane, the main component of natural gas) to K and °F
Conversion from degree Celsius to Kelvins and Fahrenheit
c) 0K (absolute zero, theoretically the coldest possible temperature) to °C and °F.

Answer:
This question is incomplete
Explanation:
This question is incomplete because the result of the described experiment would have better determined the type of scientific explanation to profer. However, the type of material that will preserve the relative hotness or temperature of the hot coffee for the longest time will be a material than can resist heat transfer. These materials tend to keep hot substances hot by not allowing the heat of the coffee to be conducted or pass through it. These materials are mostly insulators or made by placing an insulator between two heat conductors.
Generally, heat is usually transferred from a region of higher concentration to a region of lower concentration, hence when the heat is denied of this transfer, the heat will remain trapped in the "heat-donor" substance (in this case the hot coffee). Thus, the material chosen (A, B or C) will be the material that resists heat transfer the most based on the explanation above.
