When you cook pasta at home, the smell fills up the whole kitchen. What is this an example of?

1. The 1st law of thermodynamics

2. The combustion of pasta

3. The 2nd law of thermodynamics

4. The conversation of energy

The 1st law of thermodynamics and the 2nd law of themodynamics

Explanation:

The first law of thermodynamics describes the conservation of energy. It states that when heat is added to a system, it transforms to an equal amount of another form of energy. It does this by doing one or both of the following things: (1) increasing the amount of internal energy within the system; and/or (2) doing external work by leaving the system, thereby affecting the area around the system.

The second law of thermodynamics states that no reaction is completely efficient and that heat is always transferred from warmer objects to colder objects. In other words, some energy is always lost to heat in any reaction, and you'll never find heat moving from colder objects to warmer objects in a system

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.

yes the answer is total mass in unchanged   : )
