When the temperature of the air in a hot air ballon increases, what happens to the volume of the gas?
Answers
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)

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.
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)
Explanation:
When piece of very hot metal releases energy into a cup of water, if the temperature of metal drops
by 426.7°C, and the final temperature of the metal is 31.2°C, what was the initial temperature of
the metal?
Answers
Answer: The answer is 457.9
Explanation: Realistically all you have to do is add both of the temperatures and then you can figure out the original heat. Since the heat drops 426.7 degrees and it comes to 31.2 degrees its 426.7 + 31.2 = 457.9.

why is beryllium-8 different from beryllium-9 in terms of the nuclear particles?
Answers
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?
Answers
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.
