Bad White [126]

Correct answer:

The relative humidity is best described as the amount of water vapor in the air at a given temperature expressed as a percentage of the water vapor capacity of the air.

What is relative humidity?

The ratio of the current absolute humidity to the highest absolute humidity is known as relative humidity (which depends on the current air temperature).

Water vapor is also measured by relative humidity, which is stated as a percentage but RELATIVE to the air's temperature. In other words, it is a comparison between the amount of water vapor that is actually present in the air and the maximum amount of vapor that is possible for the air at the current temperature.

With the same quantity of absolute/specific humidity, air will have a HIGHER relative humidity if it is cooler and a LOWER relative humidity if it is warmer because warm air may contain more water vapor (moisture) than cold air. The actual amount of moisture (absolute humidity) in the air is what we "feel" outside.

what is the point of intersection when the system of equations below is graphed on the coordinate plane -x+y=4 6x+y=-3

Ilia_Sergeevich [38]

Answer:

POINTS OF INTERSECTION ARE:

x = -1

y = 3

coordinates : (-1,3)

Coordinates :

Explanation:

Condition for intersecting lines

$\frac{a_{1}}{a_{2}}\neq\frac{b_{1}}{b_{2}}$

here

a1 ,a2 = coefficients of x (a1 = -1 , a2 = 6)

b1 ,b2 = coefficients of y(b1 = 1 , b2 = 1)

$frac{-1}{6}\neq\frac{1}{1}\neq\frac{1}{1}$

Calculation :

Here substitution method is used : Value of y from eq (1) is substitued in equation (2)

-x + y = 4

y = 4 + x.............(i)

put value of x in equation (2)

6x + y = -3

6x + 4 + x = -3 ( from i)

7x = -3 - 4

7x = -7

x = $frac{-7}{7}$

x = -1

using equation(i)

y = 4 + (-1)

y = 4 - 1

y = 3

Check:

The values of x and y should satisfy equation (1) and (2)

for equation 1

-x+y =4

= -(-1) + 3

= 1 + 3

= 4

Hence coordinates satisfy equation 1

If the length, width, and height of a box are 10.00 cm, 7.25 cm and 3.00 cm, respectively, what is the volume of the box in unit

Blizzard [7]

<u>Answer:</u>

<u>For a:</u> The volume of the box is 217.5 mL

<u>For b:</u> The volume of the box is 0.2175 L

<u>Explanation:</u>

The box is a type of cuboid.

To calculate the volume of cuboid, we use the equation:

$V=lbh$

where,

V = volume of cuboid

l = length of cuboid = 10.00 cm

b = breadth of cuboid = 7.25 cm

h = height of cuboid = 3.00 cm

Putting values in above equation, we get:

$V=10.00\times 7.25\times 3.00=217.5cm^3$

<u>For a:</u>

To convert the volume of cuboid into milliliters, we use the conversion factor:

$1mL=1cm^3$

So,

$\Rightarrow 217.5cm^3\times (\frac{1mL}{1cm^3})\\\\\Rightarrow 217.5mL$

Hence, the volume of the box is 217.5 mL

<u>For b:</u>

To convert the volume of cuboid into liters, we use the conversion factor:

$1L=1000cm^3$

So,

$\Rightarrow 217.5cm^3\times (\frac{1L}{1000cm^3})\\\\\Rightarrow 0.2175L$

Hence, the volume of the box is 0.2175 L

Ethanol is added to gasoline to produce E-15 and E-85. It promotes more complete combustion of the gasoline and is an octane boo

Artist 52 [7]

Answer:

2,2,4-trimethylpentane has the higher heat of combustion in kcal/mol.

Explanation:

Heat of combustion is defined as heat evolved on combustion of 1 mole of a substance.

2,2,4-trimethylpentane has the higher heat of combustion in kcal/mol.

Heat combustion of 2,2,4-trimethylpentane = (1304 kcal/mol) and

$C_8H_{18}+\frac{25}{2}O_2\rightarrow 8CO_2+9H_2O,\Delta H=-1,304 kcal/mol$

1 mole of 2,2,4-trimethylpentane on combustion gives 8 mole sof carbon dioxide gas and 9 moles of water.

Heat combustion of ethanol = (327 kcal/mol)

$C_2H_5OH+3O_2\rightarrow 2CO_2+3H_2O,\Delta H=-327kcal/mol$

1 mole of ethanol on combustion gives 2 moles of carbon dioxide gas and 3 mole of water.

Heat combustion of ethanol < Heat combustion of 2,2,4-trimethylpentane
