Hello!
In this case, since the first law of thermodynamics allows us to understand how the energy behaves when heat and work are involved during a process, we can mathematically define it as:
Whereas Q is the heat added to the system, W the work done by the system and ΔU the change in the internal energy, we can notice that since 97.0 J of work are done on the system it would be negative and the given off heat is also heat due to the used convention; therefore the change in its internal energy turns out:

Answer:
The answer is 28 gram.
28 gram of Nitrogen gas are found in 22.4 l in Nitrogen gas
Loschmidt's constant is referred to as Avogadro's number (they are the same). Their values are 6.02 times 10 to the -34 power.
The heat energy from the fire is transferred to the pot by
- <em>radiation</em> — the hot coals radiate heat to the pot.
- <em>convection</em> — the hot gases from the fire travel upward until they reach the pot
The pot absorbs the heat energy and <em>conducts</em> the heat to the water inside.
The hot water <em>conducts</em> heat to the peas in three steps:
- warming the frozen ice and peas to 0 °C.
- thawing the ice and peas at 0 °C.
- heating the peas to 100 °C and cooking them at that temperature.
<em>Note</em>: Heat always flows spontaneously from a hotter to a cooler object.
Answer:
CaO - inorganic
C₂H₄(OH)₂ - organic
Ca(OH)₂ - inorganic
CH₄ - organic
NaCl - inorganic
C₃H₈ - organic
Explanation:
Organic compounds have carbon (C) in it.
For example, CaO has calcium and oxygen, but no carbon so it's an inorganic compound. However, C₂H₄(OH)₂ does have carbon, making it an organic compound.
