According to the combined gas law, the pressure exerted by a gas is:

1 answer:

3 0

Answer : The correct option is, (d) inversely proportional to volume and directly proportional to the kelvin temperature

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto \frac{1}{V}$

Charles' Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

$P\propto T$

Combined gas law : It is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{PV}{T}=K$

or,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

From the above information we conclude that the pressure exerted by a gas is inversely proportional to volume and directly proportional to the kelvin temperature.

Hence, the correct option is, (d)

Carbohydrate loading Group of answer choices involves a reduction in the intensity of workouts with a corresponding increase in

SOVA2 [1]

Answer:

the correct option would be:

The group of response options implies a reduction in the intensity of the workouts with a corresponding increase in the percentage of carbohydrate intake for several days before a competition.

Since the carbohydrate load is an increase in glycogen reserves as an energy source accompanied by a decrease in muscle demand. This is often used in high-performance activities, where strict competencies are required.

Although today some professionals do not support that, but rather support a diet with carbohydrates and proteins.

Explanation:

Carbohydrate loading increases glycogen reserves, it is accompanied by a muscle rest plan, without fatigue of muscle fibers.

The purpose of this is to exhaust the muscle fibers in maximum demands such as the competencies, ensuring a necessary energy source that supplies this reaction, for which glycogen reserves are needed.

Which best describes a chain reaction associated with a nuclear reaction? Neutrons released during a fusion reaction cause other

atroni [7]

The statement that describes a chain reaction brought about by a nuclear reaction is "neutrons <span>released during a fission reaction cause other nuclei to split." This is applicable to fission reactions only wherein atoms split and produce neutrons that also cause further atoms to split, thus creating a chain or series of reactions.</span>

Which atomic model shows the atom as a positively charged sphere with negatively charged electrons spread throughout

tankabanditka [31]

Answer:

B) Thomson's Model

Explanation:

Dalton's Model simply consisted of small spheres that represented atoms, and Bohr's model had a nucleus in the center with electrons orbiting in strict orbits, not randomly spread throughout. Thomson's plum pudding model, however, had an overall positively charged atom with many electrons spread throughout. If you search up "Plum Pudding Model" you can visually understand this.
