When the dew point temperature and air temperature are equal, the air is said to be saturated. Dew point temperature is NEVER GREATER than the air temperature. Therefore, if the air cools, moisture must be removed from the air and this is accomplished through condensation.

Select the keyword or phrase that will best complete each sentence. law is a gas law that relates pressure and volume and states

kondor19780726 [428]

Answer:

Find answers below.

Explanation:

1. Boyle's law is a gas law that relates pressure and volume and states that for a fixed amount of gas at constant temperature, the pressure and volume of the gas are directly related.

Mathematically, Boyle's law is given by;

$PV = K$

$P_{1}V_{1} = P_{2}V_{2}$

Where;

P1 and P2 represents the initial and final pressures respectively.

V1 and V2 represents the initial and final volumes respectively.

2. Charles law is a gas law that states that for a fixed amount of gas at constant pressure, the volume of the gas is propotional to its Kelvin temperature.

Mathematically, Charles is given by;

$VT = K$

$\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}$

Where;

V1 and V2 represents the initial and final volumes respectively.

T1 and T2 represents the initial and final temperatures respectively.

3. Dalton law is a law that states that the total pressure of a gas mixture is equal to the sum of the partial pressure of its component gases.

4. Avogadro's law is a gas law that states that the volume of a gas is directly proportional to the number of moles of present when the pressure and temperature are held constant.

5. Gay Lussac's law is a gas law that states for a fixed amount of gas at constant volume, the pressure of the gas is directly proportional to its Kelvin temperature.

Mathematically, Gay Lussac's law is given by;

$PT = K$

$\frac{P1}{T1} = \frac{P2}{T2}$

6. The combined gas law is a gas law that relates pressure, volume, and temperature.

7. The ideal gas law is the equation PV = nRT

Where;

P is the pressure.

V is the volume.

n is the number of moles of substance.

R is the ideal gas constant.

T is the temperature.

A 38-lb child is prescribed acyclovir for chicken pox in an amount of 80 mg/ kg body weight per day to be divided in four doses

Svetach [21]

Answer:

$\large \boxed{\text{Two tablets per day; half a tablet per dose}}$

Explanation:

1. Convert pounds to kilograms

$\text{Body weight} = \text{38 lb} \times \dfrac{\text{1 kg}}{\text{2.205 kg}} = \text{17.2 kg}$

2. Convert kilograms of body weight to milligrams of acyclovir

$\text{Mass of acyclovir} = \text{17.2 kg} \times \dfrac{\text{80 mg acyclovir}}{\text{1 kg}} = \text{1380 mg acyclovir }$

3. Convert milligrams of acyclovir to number of tablets

$\text{No. of tablets} = \text{1380 mg} \times \dfrac{\text{1 tablet}}{\text{700 mg}} = \textbf{2 tablets}$

4. Calculate the tablets per dose

The child must receive two tablets in four doses.

$\text{Tablets per dose} = \dfrac{\text{2 tablets}}{\text{4 doses}} = \textbf{0.5 tablets per dose}\\\\\text{The child must receive $\large \boxed{\textbf{two tablets per day and half a tablet per dose}}$}$
