Answer:

Warm Room

Explanation:

Let's establish two things first.

Sound is a form of energy.
Waves are made by the oscillation (up, down and sideways movement) of partials. When partials oscillate, they transfer energy by bumping into each other.

Sound wave are waves that are created by the oscillation of air particles and carry sound energy from point A to point B.

In a warm room, the air particles have higher energy compared to a cold room. Hence, they bump into each other more frequently. 

This allow them to transfer the sound energy quickly and easily from one partial to another.

Hence, sound travels faster in warm room then in cold room.

Answer:

Explanation:

Sound travels outwards from the source in all directions. So there you have it sound does travel faster in warm air BUT it may appear to travel farther in cold air. This is how that works……if the air close to the ground is colder than the air above it then sound waves travelling upwards will be bent downwards.

Answer:

The answer is below

Explanation:

A) The method of extracting essential oils from aromatic plants is important however, the process of distillation is the main method for extracting the aromatic parts of plants.

B) The condenser fan plays an important role on circulating the air across the coil to facilitate heat transfer. The condenser refrigerant and pumps it to a coil in the form of a hot gas.

Cars run on gasoline, where octane (C8H18) is the principle component. This combustion reaction is responsible for generating en

Bezzdna [24]

Answer:

10.19 g CO₂

4.69 g H₂O

Explanation:

The combustion reaction of Octane is:

C₈H₁₈ → 8CO₂ + 9H₂O

To calculate the mass of CO₂ and H₂O produced, we need to know the mass of octane combusted.

We calculate the mass of Octane from the given volume and density, using the following conversion factors:

1 gallon = 3.785 L

1 L = 1000 mL

Now we convert 1.24 gallons to mL:

1.24 gallon * $\frac{3.785L}{1gallon} *\frac{1000mL}{1L} =$ 4693.4 mL

We calculate the mass of Octane:

4693.4 mL * 0.703 g/mL = 3.30 g Octane

Now we use the stoichiometric ratios and molecular weights to calculate the mass of CO₂ and H₂O:

CO₂ ⇒ 3.30 g Octane ÷ 114g/mol * $\frac{8molCO_{2}}{1molOctane}$ * 44 g/mol = 10.19 g CO₂

H₂O ⇒ 3.30 g Octane ÷ 114g/mol * $\frac{9molH_{2}O}{1molOctane}$ * 18 g/mol = 4.69 g H₂O

What makes the carbon cycle so important? What step in the carbon cycle makes carbon readily available for plants?

iris [78.8K]

Without the carbon cycle we wouln't have air to breathe, we would die due to the lack of air.

Plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.

Why do only some salts dissolve ?are there any rules which tell you which will?

Vadim26 [7]

Insoluble salts are ionic compounds that are insoluble in water: the salt continues to exist as a solid rather than dissolving in the liquid. ... When a salt such as sodium chloride (table salt) dissolves in water, its ionic lattice is pulled apart so that the individual sodium and chloride ions go into solution.
