Consider a gas in a container that can adjust its volume to maintain constant pressure. Suppose the gas is cooled. What happens

to the gas particles with the decrease in temperature? What happens to the volume of the container?

Answer:

The volume will also decrease.

Explanation:

This illustration clearly indicates Boyle's law.

Boyle's law states that the volume of a fixed mass of gas is directly proportional to the absolute temperature, provided the pressure remains constant. Mathematically, it is represented as:

V & T

V = KT

K = V/T

V1/T1 = V2/T2 =... = Vn/Tn

Where:

T1 and T2 are the initial and final temperature respectively, measured in Kelvin.

V1 and V2 are the initial and final volume of the gas respectively.

From the illustration above, the volume is directly proportional to the temperature. This implies that as the temperature increases, the volume will also increase and as the temperature decreases, the volume also will decrease.

What is the pH of a 3.5 x 10-^6 M solution of HCl?
Svetach [21]

Answer:

5.46

Explanation:

From the question,

pH this can be defined as the acidity or alkalinity of a solution.

The expression for pH is given as

pH = -log(H⁺)...................... Equation 1

Where H⁺ = Hydrogen ion of HCL

Given: H⁺ = 3.5×10⁻⁶ M

Substitite this value into equation 1

pH = -log(3.5×10⁻⁶)

pH = 5.46

Hence the pH of HCl is 5.46

________ is an indication of how near the air is to saturation rather than the actual quantity of water vapor in the air.
hjlf

Answer: Relative humidity

Explanation:

Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor has higher relative humidity in cool air than in warm air. A related parameter to that regard is that of dew point.

Why does the mass number only include the number of protons and the neutrons (not electrons)?
docker41 [41]

Answer:

The mass number (A) of an atom is the total number of protons and neutrons in its nucleus. ... Because electrons have virtually no mass, just about all the mass of an atom is in its protons and neutrons. Therefore, the total number of protons and neutrons in an atom determines its mass in atomic mass units (Table 4.5. 1).
