Answer:
The pressure would increase because the volume of space the gas takes up decreases once the bottle is squeezed. There is less room for the gas particles to move around meaning more collisions between the particles occur.
Explanation:
Answer: Option (b) is the correct answer.
Explanation:
When the cake is baked then due to the heat provided to it there will occur movement of its molecules.
As a result, molecules will gain kinetic energy due to which there will occur collisions between them.
Also, 
Hence, more is the heat provided to the cake more will be the kinetic energy of its molecules due to which when we touch it, it feels hot.
Thus, we can conclude that molecules in the cake are moving faster than molecules in the skin, best explains why the cake feels hot.
Oxygen has 8 protons and 10 electrons due to the addition of 2 electrons, determined from the ion charge. Likewise an ion of potassium has 19 protons and 18 electrons. Charge on fluorine would be -1 and charge on calcium would be +2. Atomic number is the same as the number of protons, so it would be 6, the mass number is the sum of protons and neutrons which would be 13, and the charge is 0, as it is an atom and not an ion.
The atoms of the reactant rearrange to form new products.
