Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 970 g

volume = 36 mL

The density of the object is

$density = \frac{970}{36} \\ 26.944444...$

We have the final answer as

Hope this helps you

Answer:

The answer to your question is: C. The specific latent heat of fusion

Explanation:

A. The specific latent heat of vaporization Specific latent heat of vaporization indicates the transition from liquid to vapor, but we are not looking for this definition. This answer is wrong.

B. The specific heat indicates the amount of heat needed to increase the temperature of water 1°C, so this answer is wrong.

C. The specific latent heat of fusion . This heat indicate the transition from solid ie to liquid, so this is the right answer.

D. The internal energy measures the energy of the molecules of a substance, so this answer is wrong.

Which sentence explains why gases can change volume but liquids cannot?

choli [55]

Answer: Molecules of gas are usually far apart and can be compressed unlike molecules of liquids.

Explanation:

The molecules of gases are usually far apart, moving freely and randomly, occupying extra space in the containing vessel. Hence, when compressed to become closely packed, gases have lower volume.

However, unlike gases, the molecules of a liquid are restricted, move less freely and occupy no extra space. Hence, liquids cannot be compressed, and their volume remains the same in their containing vessel.

The partial pressure of CO2 inside a bottle of soft drink is 4.0 atm at 25°C. The solubility of CO2 is 0.12 mol/L. When the bott

navik [9.2K]

We can solve this problem by using Henry's law.
Henry's law states that the amount of dissolved gas is proportional to its partial pressure.
$C=kP$
C is <span>the solubility of a gas.
</span><span>k is Henry's law constant.
</span><span>P is the partial pressure of the gas.
</span>We can calculate the constant from the first piece of information and then use Henry's law to calculate solubility in open drink.
0.12=4k
k=0.03
Now we can calculate the solubility in open drink.
$C_o=kP_o
$
$C_o=0.03 \cdot 3\cdot 10^{-4}=0.09\cdot 10^{-4} \frac{mol}{L}$
Now we need to convert it to g/L. One mol of CO2 is 44.01<span>g.
</span>The final answer is:
$C_o=0.09\cdot 10^{-4}\cdot 44,01=3.4\cdot 10^{-4} \frac{g}{L}$
