The Big Bang Theory is a hypothesis that states that all matter
and energy were at one time compressed into a small volume
and then _________
Answers
Answer:
I’m not sure how they want you to answer the fill in blank.
Explanation:
The Big Bang is a theory where 14 billions years ago all matter and energy in the universe was compressed into an extremely small volume that exploded and began expanding in all directions.
The big bang theory is a hypothesis that states that all matter and energy were compressed into a small volume at one time and then expanded outward.
What is Big Bang Theory?The big bang model of the universe can be described as the model to identify the beginning of the universe. The big bang model is a cosmological model which is described by the software development life cycle.
The Big Bang theory is the dominant model of the observable universe from its beginnings to large-scale evolution. This model explains how the universe is expanded from a state of high density and temperature. It provides an explanation for phenomena, such as cosmic microwave background radiation, the abundance of light elements, and large-scale structure.
Due to the big bang as we know, the universe has been created existing about 12 - 15 billion years ago. According to the theory that the Big bang was a gigantic explosion that formed all of the energy and mass in less than a second in the universe.

Which statements in this passage about volcanoes do not contain factual errors?
The Hawaiian islands are known for their volcanic activities. In fact, the islands were formed from volcanoes. Before a volcano erupts, earthquake activity beneath the volcano decreases. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano. When a volcano erupts, the amount of carbon dioxide and sulfur dioxide emitted decreases. Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.
(I couldn't find the science subject so I just put chemistry)
Answers
Answer:
The answers are
1. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.
2. Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.
Explanation:
When a volcano is near eruption Earthquake activity gets stronger and stronger. Scientists use a wide variety of techniques to monitor volcanoes, including seismographic detection of the earthquakes and tremor that almost always precede eruptions, precise measurements of ground deformation that often accompanies the rise of magma, changes in volcanic gas emissions, and changes in gravity and.
Scientists can use the FTIR or Fourier Transform Infrared Spectrometer to measure dissolved volatile concentrations as described above or can be used to measure several gases emitted from a volcano simultaneously. The device can be used both as an open-path or closed-path system. I had just taken the test and got the question right as well
The statements in this passage about volcanoes which do not contain factual errors are scientists use seismometers to measure the earthquake activity that occurs beneath a volcano.Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.
What are errors?Errors in chemical analysis are defined as a result when there is a difference between observed value and the true value.If the magnitude of errors is large , it results in a decrease in accuracy, reproducibility, and precision.
There are three types of errors present:1) random error 2) systematic error 3) human error.The cause of random errors are difficult to quantify while the human errors can be minimized by taking a range of readings or observations to reduce the error.
Errors while measuring boiling point may be human errors while noting down the boiling temperature or instrumental error or systematic error if there is a fault in the thermometer.

What was important about the Hydrogen bright line emission spectrum?
Answers
Answer:
The emission spectrum lines are the changes in the quantum energy levels of the single electron in the Hydrogen atom.
Explanation:
Electrons move around the hydrogen atom in electron waves patterns. These waves occur in distinct quantum energy levels.
The change from one quantum energy level to another energy level has a definite energy level change. There is a wave length associated with each change in energy levels. These wave lengths have a color associated with them.
Low energy level changes have long wave lengths associated with them giving red and orange colors.
High energy level changes have short wave lengths associated with them giving blue and violet colors.
Note each atom has a unique emission spectrum associated with the energy levels and electron structure of the atom. Helium was first discovered by looking at its emission spectrum as seen in the sun.
