Baking soda added to water raises the temperature slightly. Chemical reactions are either endothermic or exothermic. Endothermic means you have to put energy in to make the reaction go while exothermic means there's energy left over. Left over heat will raise the temperature. Baking soda and water is exothermic and so the water gets a little warmer. This is because the binding energy of the chemical bonds of the products has an excess over the binding energy of the components. Therefore, energy is released and the water warms up.

Basically its just an air like fluid with chemicals.... just like air it just goes as it pleases and fills space
Answer:
Photon is absorbed by the atom
Explanation:
For an electron to jump from lower energy level to higher energy level it needs some energy. This process can only take place when the atom absorbs energy, which can be in the form of photons. When the electron jumps to higher energy levels, it is known as excited state and it is not stable. So the electron will try to come back to lower energy level and in that process it will release energy.
Its either B or C but im leaning more towards B but i could be wrong
