Answer:

Diagram Z

Explanation:

A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.

Answer:

Diagram Y

Explanation:

Osmosis is the passive movement of water molecules across (into or out of) a cell membrane. "Passive" means that the process occurs automatically without the need for chemical energy.

In the diagrams above, a plant cell is shown as it would appear in a solution with a solute concentration more than its own (X), a solution with a solute concentration equal to its own (Y), and a solution with a solute concentration less than it own (Z). The movement of water is toward the area of more solute concentration (and therefore less water concentration).

The answer, then, is Diagram Y.

When the pressure of a gas is decreased from 3.40 atm to 2.60 atm, the temperature of the gas will decrease from 60.0 degree celsius to 45.88 degree celsius.

Gay -Lussac law states that the pressure and temperature is in direct proportions. Thus, pressure increases with an increase in temperature. The relation can be mathematically expressed as follows:

P/T = a constant. Hence,

P1/T1 = P2/T2

The initial pressure of the sample is given, 3.46 atm and the initial temperature is 60 °C. The final temperature of the gas when gas the expand to the lower pressure of 2.60 atm is calculated as follows:

[tex]T_{2} = \frac{P_{2}T_{1}}{P_{1}}[/tex]

    = (60 °C× 2.60 atm) / 3.40 atm

    = 45.88 °C.

Hence, the final temperature of the gas which is expanded from the pressure of 3.40 atm to 2.60 atm with an initial temperature of 60 °C is  45.88  °C.

The buffer that is adjusted to control acid-base balance is referred to as a bicarbonate buffer.

This consists of a weak acid and its conjugate base, or vice versa and resist changes in the pH of the solution.

The bicarbonate buffer is involved in acid-base homeostasis by removing CO2 and hydrogen ions, respectively, from the body.

The volume of the gas when the container is cooled from a temperature of 300 K to 200 K is 0.83 L

Charles' law states as follow:

V₁ / T₁ = V₂ / T₂

Where

From the question given above, the following data were obtained

V₁ / T₁ = V₂ / T₂

1.25 / 300 = V₂ / 200

Cross multiply

300 × V₂ = 1.25 × 200

Divide both side by 300

V₂ = (1.25 × 200) / 300

V₂ = 0.83 L

Answer:

There is no net loss of energy from the collisions.

Explanation:

Gas particles are constantly colliding with each other and the walls of their container. These collisions are elastic; that is, there is no net loss of energy from the collisions. Gas particles are small and the total volume occupied by gas molecules is negligible relative to the total volume of their container.

Explanation:

According to Avogadro's law equal volume of all gases at the same temperature and pressure contain equal number of molecules. At STP one mole of any gas behaving ideally occupies a volume of 22.414 L.

The volume occupied by one mole of a substance at a given temperature and pressure is defined as the molar volume at that temperature and pressure. The value of molar volume of an ideal gas at STP is important in stoichiometric calculations.

At STP, the number of molecules of a gas is given as:

Number of molecules of a gas (N) = V₀ in L /  22.414 × 6.022 × 10²³

Here  V₀ in L = 16500 = 16.5 L

N =  16.5 / 22.414  × 6.022 × 10²³

N = 4.433 × 10²³

Thus the number of molecules present is 4.432 × 10²³.

The pressure in a 8.00 L tank with 50.5 grams of chlorine gas at 365 K is 2.67atm.

The pressure of a given mass of gas can be calculated using the following formula:

PV = nRT

Where;

The number of moles in 50.5g of Chlorine gas is as follows:

moles = 50.5/70.91

moles = 0.71mol

P × 8 = 0.71 × 0.0821 × 365

8P = 21..34

P = 21.34/8

P = 2.67atm

Therefore, the pressure in a 8.00 L tank with 50.5 grams of chlorine gas at 365 K is 2.67atm.

According to the Gay-Lussac's law, as volume is constant the temperature must be decreased to 31.6°C.

Gay-Lussac's law is defined as a gas law which states that the pressure which is exerted by the gas directly varies with its temperature and at a constant volume.The law was proposed by Joseph Gay-Lussac in the year 1808.

The pressure of the gas at constant volume reduces constantly as it is cooled till it undergoes condensation .The law is given by the formula, V₁/T₁=V₂/T₂, which on substitution gives T₂=95×100/300=31.6 °C.The container in Gay-Lussac's law is considered to be rigid  in contrast to the container present in Charle's law.

Thus, as per  Gay-Lussac's law, as volume is constant the temperature must be decreased to 31.6°C.

A high pressure area is an area where the air sinks. As it does, it warms up by the adiabatic effect of a greater pressure and that causes the clouds to evaporate, giving place to a clear sky

Explanation:

A high-stress area, high, or anticyclone, is a location in which the atmospheric stress on the surface of the planet is more than its surrounding environment.

In a high-Pressure system, it has better pressure in its center than in the regions around it. Winds blow away from excessive pressure.

Swirling withinside the contrary route from a low-stress system, the winds of an excessive pressure system rotates clockwise north of the equator and counterclockwise south of the equator.

Hence, these are the characteristics of high-pressure system.
