Answer 1

Q7. A fizzing sound was overheard shadowed by the rushing out of bubbles from the bottle dipped in hot water. There was also a sound perceived in the bottle to be found in cold water but not as much as in bottle A.

Q8. There was amassed gas inside the bottle.

Q9. The hot water surges the temperature of the soda drink inside the bottle. As the temperature increases, more gas is accumulated inside the bottle. This reasons the fizzing sound.

Q10. The observation in the bottle of cooking oil is not the same as in the soda drinks.

Q11. There was little gas out in the bottle of cooking oil for the reason of its structure. We know that soda drink is carbonated. The great temperature free the gas from the soda drinks.

Answer 2

Answer no 7. A fizzing sound was overheard shadowed by the rushing out of bubbles from the bottle dipped in plight. There was also a sound perceived within the bottle to be found in cold water but not the maximum amount as in bottle A.

Answer no 8. There was amassed gas inside the bottle.

Answer no 9. the new water surges the temperature of the soda drink inside the bottle. because the temperature increases, more gas is accumulated inside the bottle. This reasons the fizzing sound.

Answer no 10. The observation within the bottle of vegetable oil isn't the identical as within the soda drinks.

Answer no 11. There was little gas get in the bottle of vegetable oil for the rationale of its structure. we all know that soda drink is carbonated. the good temperature free the gas from the soda drinks.

Further Explanation

State equations are thermodynamic equations that describe the state of matter under a set of physical conditions. A state equation is a constitutive equation that provides a mathematical relationship between two or more state functions related to the matter, such as temperature, pressure, volume, and internal energy. State equations are useful in describing the properties of fluids, fluid mixtures, solids, and even the inside of a star.

The most common use of a state equation is in predicting the state of gases and liquids. One of the simplest state equations in this use is the ideal gas law, which is quite accurate in predicting the state of the gas at low pressure and high temperature. But this equation becomes increasingly inaccurate at higher pressures and lower temperatures and fails to predict condensation from gases to liquids. However, several more accurate state equations have been developed for various gases and liquids. At present, there is no single state equation that can accurately estimate the properties of all substances under all conditions.

The ideal gas equation is the state equation of an ideal gas. This equation is a good approach to the characteristics of some gases under certain conditions. This equation was first coined by Émile Clapeyron in 1834 as a combination of Boyle's Law and Charles's Law. This equation is commonly written as

PV = nRT

where P is the absolute pressure on the gas, V is the volume, n is the number of particles in the gas (in moles), T is the temperature in kelvin units, and R is the ideal gas constant, which is 0.08205 L atm mol-1 K-1.

This equation can also be derived from kinetic theory, which was coined separately by August Krönig in 1856 and Rudolf Clausius in 1857. Universal gas constants were discovered and first introduced to the ideal gas law by Dmitri Mendeleev in 1874. The ideal gas equation is useful, especially in gas stoichiometry.
