what is the relationship between chemical and electrical energy
Answer:
Electrochemistry,
Explanation:
Electrochemistry is a branch of chemistry concerned with the relation between electricity and chemical change. Many spontaneously occurring chemical reactions liberate electrical energy, and some of these reactions are used in batteries and fuel cells to produce electric power.

Research the validity of ONE of the following hypnosis claims using reputable sources. (No blogs, social media posts, etc.)
1.Hypnosis can help people stop smoking.
2. Hypnosis can help people with weight loss.
A. To what extent does hypnosis work in regards to these behaviors?
B. Would you recommend them? Why or why not?
C. What sources did you use to find your answers.
Answer:
1. Hypnosis can help people stop smoking.(Yes)
To what extent does hypnosis work in regards to these behaviors?
A study by McNeilly and colleagues found that hypnosis may help quitters to focus on their own resources to curb cigarette cravings. Other researchers have suggested that success rates are caused by the relaxation effects of hypnosis. These might allow people to cope with nicotine addiction and nicotine withdrawal.
Would you recommend them? Why or why not?
I wouldn't recommend it because, The evidence for hypnosis as a successful smoking cessation method is a mixed bag. Some studies have seen high success rates, whilst others are more modest. A review of 59 different trials found that hypnosis is often better than no support at all.( so its a risk)

Answer:
I think its electromagnetic spectrum
Answer:
Radiant energy is energy that travels in waves and can travel through space. The sun gives off radiant energy and is important here on earth for many natural processes to occur. The electromagnetic spectrum is the range of all forms of radiant energy from gamma rays to radio waves.
Explanation:
When the temperature of the air in a hot air ballon increases, what happens to the volume of the gas?
Answer:
As the temperature increases, the gas particles absorb more heat energy. They speed up and move farther away from one another. So the increase in temperature causes an increase in volume. (Boyles Law)

since we cannot measure to absolute zero, how can we determine what the volume will be at that temperature?
Answer:
We can measure volumes approaching absolute zero and then predict what the volume would be at absolute zero.
Since there is NO molecular motion at absolute zero, the volume of a balloon at absolute zero should be zero.
If you headed to the deepest recesses of intergalactic space, shielded from starlight, the only thing that would heat you up would be the Big Bang's leftover glow: the cosmic microwave background at 2olume.ht v725 K. At that temperature, the balloon would have a volume.
Charles' Law asserts that a gas's volume (V) and temperature (T), which must be expressed in Kelvin, are directly proportional to one another. A change in temperature of one Kelvin unit corresponds to a change in one Celsius degree. Never forget that the value 0 on the Kelvin scale corresponds to -273 or "Absolute Zero."
What will the volume be at absolute zero, and how can we calculate it?Charles's Law, V = a T+ b, is used to calculate absolute zero once the mass measurements are transformed to high and low temperature gas volumes.
The volume of an ideal gas would theoretically be 0 at absolute zero, and there would be no more molecular motion. Actually, above this temperature, all gases condense into solids or liquids.
According to Boyle's Law, gas volume grows as pressure lowers. Charles' Law states that when the temperature rises, the volume of the gas increases.
Gases compress infinitely as the temperature is lowered because there is a linear relationship between temperature and pressure for the majority of gases (see gas laws). The volume of an ideal gas would theoretically be 0 at absolute zero, and there would be no more molecular motion.

Explanation:
Pots and pans that are used for cooking are often
made of copper, aluminum, and iron. Explain how metallic bonding makes these
metals suitable for this use.
Cooking materials are made of copper, aluminum, and iron because they contain free, mobile electrons owing to the metallic bond.
Metallic bonding involves a sea of electrons that is bonded to metal cations by electrostatic attraction. The electrons in the metallic bond are free to move around the material.
Because there are free electrons, when the material is heated, the electrons receive energy and move faster, this energy spreads throughout the material by conduction.
Hence, good conductors of heat such as copper, aluminum, and iron are used for cooking materials.

why is beryllium-8 different from beryllium-9 in terms of the nuclear particles?
Answer:
Beryllium-8 (8Be, Be-8) is a radionuclide with 4 neutrons and 4 protons. It is an unbound resonance and nominally an isotope of beryllium. It decays into two alpha particles with a half-life on the order of 10−16 seconds; this has important ramifications in stellar nucleosynthesis as it creates a bottleneck in the creation of heavier chemical elements. The properties of 8Be have also led to speculation on the fine tuning of the Universe, and theoretical investigations on cosmological evolution had 8Be been stable.

Allison adds ice cubes to water which is at room temperature. Over time, the ice melts.
Read the statement above. How does adding ice to the room temperature liquid change the average kinetic energy of the particles of the
liquid?
Adding ice to the liquid decreases the average kinetic energy of the particles of the liquid.
The temperature of a substance is defined as a measure of the average kinetic energy of the molecules of the substance. The average kinetic energy of the molecules of a substance is directly proportional to the temperature of the substance.
This implies that if I increase the temperature of a substance, the average kinetic energy of the molecules of the substance increases and vice versa.
Ice is at a lower temperature than water at room temperature. Thus, adding ice to water at room temperature decreases the temperature of the water and consequently decreases the average kinetic energy of its particles.
