Which list includes three forms of energy?(1) chemical, mechanical, electromagnetic(2) chemical, mechanical, temperature(3) ther
bekas [8.4K]

The capacity to do work is said to be energy. It is a quantitative property and conserved quantity. It can exist in different forms such mechanical energy, sound energy, chemical energy etc. According to law of conservation of energy, energy can neither be created nor be destroyed implies there is no loss of energy occurs during any process or any reaction only conversion of energy takes place.

Temperature and pressure are not forms of energy, they are physical properties.

Hence, first option (1) is the correct answer i.e. chemical, mechanical, electromagnetic are three forms of energy.

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 <u>inversely</u> 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 <u>proportional</u>. We see this in the formula \frac{V1}{T1} = \frac{V2}{T2}.

Guy-Lussac's Law-  As temperature increases, pressure increases, so they are <u>proportional</u>. 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
