What is chemical potential energy?

Chemistry
1 answer:
tigry1 [53]2 years ago
7 0

Chemical potential energy: chemical potential of a species is energy that can be absorbed or released due to a change of the particle number of the given species, in a chemical reaction or phase transition

Gasoline used as kinetic energy: the various chemicals that make up gasoline contain a large amount of chemical potential energy that is released when the gasoline is burned in a controlled way in the engine of the car. The release of that energy does two things. Some of the potential energy is transformed into work, which is used to move the car

Dynamite used as kinetic energy: the dynamite being used was most likely made of nitroglycerin. Once the dynamite explodes from a percussion force (then breaking of weak bonds to releasing the raw atom) the energy is then converted to thermal, kinetic, and sound energy.

A cylinder containing 14.71 L of helium gas at a pressure of 169.1 atm is to be used to fill toy balloons to a pressure of 1.086
Komok [63]

Answer:

The number of balloons is 948.8.

Explanation:

The number of balloons can be calculated as follows:

N = \frac{V_{f}}{V_{T}}

Where:

V_{f}: is the volume at 1.086 atm

V_{T}: is the balloon volume = 2.414 L  

The volume at 1.086 atm can be found using Boyle's law:

P_{i}V_{i} = P_{f}V_{f}

V_{f} = \frac{P_{i}V_{i}}{P_{f}} = \frac{169.1 atm*14.71 L}{1.086 atm} = 2290.5 L

Now, the number of balloons is:

N = \frac{V_{f}}{V_{T}} = \frac{2290.5 L}{2.414 L} = 948.8

Therefore, the number of balloons is 948.8.

I hope it helps you!

What is the ultimate end of a high mass star that has a core about 2.8x the mass of our sun?
jolli1 [7]

Answer:

A

Explanation:

It is formed after the star has ended its star cycle into a supernova. The star collapsed into a neutron star that is smaller than the progenitor star but has inherited angular momentum. IT, therefore, spins faster emitting electromagnetic radiation that seems to pulsate.
