Answer:
Yes<em>!</em>
Explanation:
<u>Liquids</u> & <u>gases</u> are poor conductors, but they can make heat (thermal energy) travel quickly from one point to another. ... ~ When waves of heat (thermal energy) travel through empty space and transparent mediums, heat transfer by radiation occurs. <u>Solids, liquids,</u> & <u>gases</u> can all be heated by radiation.

Answer:The chemical energy
Explanation:because The chemical energy in the food you eat is changed into another kind of chemical energy that your body can use. Your body then uses that energy to give you the kinetic energy that you use in everything you do.

Explanation:
d =

V
m = d×V
V =

d
DENSITY
Density is defined as mass per unit volume.
d =
m
V
Example:
A brick of salt measuring 10.0 cm x 10.0 cm x 2.00 cm has a mass of 433 g. What is its density?
Step 1: Calculate the volume
V = lwh = 10.0 cm × 10.0 cm × 2.00 cm = 200 cm³
Step 2: Calculate the density
d =

We can rearrange this to get the expression for the mass.
m = d×V
Example:
If 500 mL of a liquid has a density of 1.11 g/mL, what is its mass?
m = d×V = 500 mL ×

Example:
What is the volume of a bar of gold that has a mass of 14.83 kg. The density of gold is 19.32 g/cm³.
Step 1: Convert kilograms to grams.

Answer:
A evaperation
Explanation:
humidity would not change the water level condensation is the collection of water on objects and that would cause more not less water and precipitation is rain fall A would be the correct answer.
Answer:
The molality of the solution is 3.45 mol/kg
Explanation:
Molality is a type of concentration which shows the moles of solute contained in 1 kg of solvent.
Moles of salt (KCl) = 1.12 moles
Moles of solvent (H₂O) = 18 moles
Let's convert the moles of solvent to mass (mol . molar mass)
18 m . 18g/m = 324 grams
We convert grams to kg → 324 g / 1000 = 0.324 kg
Now we can reach molality
1.12mol / 0.324 kg = 3.45 m
