Sea water, a solution composed of a variety of salts dissolved in water. The salt is the . Soda water, a solution composed of ca

VladimirAG [237]

Answer:

In sea water;

The salt is the solute while the water is the solvent

In soda water;

The water is the solvent, the carbon dioxide is the solute

In air;

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes

Explanation:

A solution is a homogeneous mixture of two or more substances which includes a solvent and a solute. A solute in a solution is dissolved in the solvent of the solution.

Therefore, the solvent is the major part of a solution as it takes in the solvent to form the solution.

In sea water, a solution with a high concentration of salts

The salt is the solute while the water is the solvent

In soda water, which is a mixture of CO₂ in water,

Here we have in the soda solution, the water is the solvent while the carbon dioxide is the solute

The water is the solvent, the carbon dioxide is the solute

Air a solution made up by a mixture of Nitrogen 78%, oxygen 21%, and small amount of water carbon dioxide and argon

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes.

How much heat is absorbed by a 112.5 g sample of water when it is heated from 12.5 °C to 92.1 °C? (Specific heat capacity of wat

Alborosie

Answer:

$\boxed {\boxed {\sf37,467.72 \ Joules }}$

Explanation:

We are asked to find how much heat a sample of water absorbed. Since we are given the mass, temperature, and specific heat, we will use the following formula.

$q=mc \Delta T$

The mass (m) of the sample is 112.5 grams. The specific heat capacity of water (c) is 4.184 Joules per gram degree Celsius. The difference in temperature (ΔT) is found by subtracting the initial temperature from the final temperature.

ΔT= final temperature - initial temperature

The water was heated from 12.5 degrees Celsius to 92.1 degrees Celsius.

ΔT= 92.1 °C - 12.5 °C= 79.6°C

Now we know three variables and can substitute them into the formula,

m= 112.5 g
c= 4.184 J/g °C
ΔT= 79.6 °C

$q= (112.5 \ g )(4.184 \ J/g \textdegree C)(79.6 \textdegree C)$

Multiply the first 2 numbers. Note the units of grams cancel.

$q= (112.5 \ g *4.184 \ J/g \textdegree C)(79.6 \textdegree C)$

$q= (112.5 *4.184 \ J/ \textdegree C)(79.6 \textdegree C)$

$q= (470.7 \ J/ \textdegree C)(79.6 \textdegree C)$

Multiply again. This time the units of degrees Celsius cancel.

$q= (470.7 \ J/ \textdegree C *79.6 \textdegree C)$

$q= (470.7 \ J *79.6 )$

$q= 37467.72 \ J$

37, 467.72 Joules of heat are absorbed by the sample fo water.

LenaWriter [7]

Answer with Explanation:

The units used to express the densities of gases are different from those of solids and liquids because the particles in gas are widely separated from each other, unlike the particles in solid and liquid which are almost the same. The particles in solid are very close together. Considering it melts (if it's an ice), it will turn into a liquid and the change in volume is slightly greater only. However, if the liquid evaporates and transitions into a gas, the volume becomes largely different from its solid and liquid state. This is because the particles are much farther apart and free to move.
