Answer from: cman1280

The pressure of a gas increases four times, when the absolute temperature is increased four times, while maintaining the volume constant.

Explanation:

The expression that rules the change of temperature of ideal gases at constant volume is the Law of Gay-Lussac: pressure and temperature of gases are directly related. In the form of equations that is:

P / T = constantP₁ / T₁ = P₂ / T₂ [equation 1]

The question states that the absolute temperature is increased four times, the you can write that as T₂ = 4 × T₁, and substitute in the equation 1 to obtain:

P₁ / T₁ = P₂ / (4 × T₁)

Simplify:

P₂ = P₁ × 4 × T₁ / T₁ = P₁ × 4

That proves that the pressure also increases four times, when the absolute temperature is increased four times, while maintaining the volume constant.

Answer from: leianagaming

The pressure will also increase 4 times.

Explanation:

To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=p\\T_1=t\\P_2=?=\\T_2=4t$

Putting values in above equation, we get:

$\frac{p}{t}=\frac{P_2}{4t}\\\\P_2=4p$

Hence, the pressure will also increase 4 times.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

Answer from: Quest

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
