Predictions

The mass of the bag with air will be the sum of the mass of the bag itself and the mass of the air inside it. The mass of the air can be estimated by knowing the dimensions of the bag and the density of air at the given conditions.

The same way they are predicted in the rest of the world...not at all. It is difficult at best to predict an earthquake. Some earthquake prone areas seem to follow a regular cycle, so geologist can predict when a event "may" take place. But, so far, we don't have the technology or ability to say with any degree of certainty that an seismic event is coming.

By the position of an element on the periodic table you can tell how many protons the element has in it by looking at the number above the elements symbol. You can also find the electron configuration with that same number then you can and you can you can also tell if it is f1, f2,f3...s1,s2,d1,d2...

Volcanoes can be predicted using various monitoring techniques such as seismic activity, ground deformation, gas emissions, and thermal imaging. Scientists study these indicators to determine if an eruption is likely to occur. Advanced technology and constant monitoring help to provide early warnings and forecasts of volcanic activity.

A prediction that can be proved or disproved by experiments is that a chemical reaction will occur when two specific substances are mixed together under certain conditions. By conducting the experiment and observing the presence or absence of a reaction, the prediction can be verified.

it depends?

Are you looking at il religously like a christians beliefs in revelations

Or the Mayan calender which randomly ends at 12-21-12?

Also there are many many more theories, you need to be specific

There is no scientific evidence to suggest that animals can reliably predict earthquakes. While some anecdotal reports have suggested that certain animals behave unusually before an earthquake, these behaviors are often difficult to confirm and are not consistent enough to be relied upon as an early warning system for earthquakes.

They use five clues. 1) Frequency and type of earthquakes associated with the volcano 2) changes in slope 3) changes in gases released 4) changes in the volcano's surface temperature 5)changes in animal's behaviour

hope those help ya honey ;)

thx they really helped

i got an a +

A hypothesis is a prediction about the outcome of a test or experiment. It is an educated guess based on existing knowledge or observations, and is used to guide scientific investigations.

Yes, scientists can predict volcanic eruptions, but only to a certain extent of accuracy.

One method is to use earthquakes. Earthquakes usually increase and become more violent before a volcanic eruption

The Hertzsprung-Russell diagram predicts the relationship between a star's luminosity (brightness) and temperature, allowing astronomers to classify stars based on their properties. It shows the correlation between a star's temperature and its absolute magnitude, helping to understand their evolutionary stage and lifecycle.

A descriptive model is one that summarizes data and describes patterns or relationships in the data. It is based on observed outcomes. A prediction is a statement about what will happen in the future based on current evidence or past patterns. Combining the two, a descriptive model based on a prediction would involve using historical data or patterns to make informed guesses about future outcomes.

The answer you predict before starting the experiment is your hypothesis.

Volcano eruptions are difficult and sometimes dangerous to predict, but recent discoveries have made forecasting somewhat easier. There are many different methods, including using tiltmeters, taking seismic readings, measuring poison gasses, and using satellites. Bernard Chouet, a volcanologist, believes to have discovered the language of volcanoes and how to tell when they will erupt by using signals in seismic readings. Many of his predictions have been correct, but his theory is yet to be proven. Deciding whether to call an evacuation in the prediction of a volcano is also challenging, as the intensity of an eruption is tricky to tell. There are 33 recently active volcanoes in the United States, but less than half of them are monitored, according to the USGS, the government agency responsible for issuing warnings of hazardous volcanic activity. Sometimes, the USGS has to assume that a volcano will behave in the way it has in the past.

Before an eruption, magma (lava) moves into the area beneath the volcano and collects in the magma chamber. As it comes closer to the surface, the magma releases gases. These events can offer clues about when the eruption will take place. For example, the movement of magma produces small earthquakes and vibrations which can be detected using seismographs. Magma gathering in a chamber causes slight swelling of the volcano's slopes which can be shown using tiltmeters and geodimeters. Gases released near the volcano can be measured with correlation spectrometers for changes in quantity.

The strainmeter, by which its seismometer component detects the vibrations or shock waves that its seismograph records, is the scientific instrument that's used to predict and measure earthquakes.

A melting point can be predicted by analyzing the molecular structure of a compound. Factors such as symmetry, molecular mass, intermolecular forces, and bond types can give clues about the range of temperatures at which a substance will melt. Additionally, using computational methods and databases of similar compounds can help in predicting melting points.

Observation involves gathering information through direct or indirect means based on what is currently happening or has already occurred. Prediction, on the other hand, involves using available data to forecast or estimate the likelihood of future events or outcomes. Observations are factual descriptions of current or past events, while predictions are informed guesses about what might happen in the future based on patterns or trends.

To compare, first gather data using measurement tools or techniques. Next, analyze the data to identify patterns or trends. Finally, use this analysis to make predictions about future outcomes based on the measurements taken. Repeat the process to adjust predictions as needed.

The Periodic Table (see link) gave great insight into the chemical properties of all the elements ... for it turns out that there is a pattern to it all.

For predicting its chemical reactivity, generally you look at where it lies on the Periodic Table, which groups it with metals, semimetals, or nonmentals. Metals combine with nonmetals to form ionic compounds; nonmetals also combine with other nonmetals to form covalent compounds; and metals combine with other metals to form metal alloys (semimetals have intermediate properties). The element's location on the periodic table also defines its specific valence electron structure, and since atoms tend to react so that they have a full octet of valence electrons this will predict the specifics of its bonding behavior. For example, a metal that has only two valence electrons (like nickel) will tend to create a (+2) cation. A nonmetal that has four valence electrons (like carbon) will tend to form four (covalent) bonds.

The idea of the path of an electron being unpredictable was presented by Werner Heisenberg. It was "packaged" as "Heisenberg's uncertainty principle" and that's how we know it today. What Heisenberg actually said was that if we look at an electron, the closer we look at its momentum, the less certain we are about its position. And if we look closely at its position, the less certain we can be about its momentum. There is a trade-off when we look for precision, and we cannot have our cake and eat it too. It's one or the other as regards accuracy.

Hypothesis is the aim of the experiment. It could be to see if there is a colour change when mixing two chemicals together.

Prediction is just a guess, which could be based on evidence, data or just a wild guess. You could predict that there would be no change in colour when the two chemicals are mixed together.

A hypothesis is a proposed explanation for a phenomenon. A prediction is a statement that forecasts what will happen based on the hypothesis. An experiment is conducted to test the hypothesis and, in turn, test the accuracy of the prediction.
