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:
14
Explanation:
Silicon has atomic number 14, so its nucleus contains 14 protons
no. of protons + no. of neutrons = atomic mass number
p + n = A
14 + n = 28
n = 28 - 14 = 14
An atom of Si-28 contains 14 neutrons.
The main reason behind this is Boyle's law and Gay Lussacs law
- Gay Lussac's law states that Pressure is directly proportional to Temperature.
- Boyle's law states that Volume is inversely proportional to pressure.
If temperature will be more Pressure will be more
