Name at least three types of energy associated with a microwave

IrinaVladis [17]

I'm pretty sure what you are trying to ask for is radiative energy, light energy, and electronic energy.
Radiative since the microwave is releasing radiation,
Light since there is light inside the microwave,
Electronic since it is plugged in and uses electricity.
You can also use sound, but I don't think every microwave makes sound.

Identify the gas law that applies to the following scenario: A 36.5 liter balloon holding 2.9 moles of carbon dioxide leaks. If

jarptica [38.1K]

Answer:

Avogadro's Law; 15.1L

Explanation:

Boyle's Law- Pressure and volume are inversely related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.

Charle's Law- Gas expands/increases in volume when temperature increases, so they are proportional. We see this in the formula $\frac{V1}{T1} = \frac{V2}{T2}$ .

Guy-Lussac's Law- As temperature increases, pressure increases, so they are proportional. We see this in the formula $\frac{P1}{T1} = \frac{P2}{T2}$ .

Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula $\frac{V1}{n1} = \frac{V2}{n2}$ .

Plugging in the values based on Avogadro's Law, we'll have:

$\frac{36.5}{2.9} = \frac{V2}{1.2}$

12.6 = $\frac{V2}{1.2}$

12.6 x 1.2 = V2

15.1L =V2
