Why is magma that contains little silica less likely to erupt explosively?

Answers

Answer 1
Answer: Because there is less Silica, there isn't much pressure built up.

During an experiment a student measured the temperature of water while it boiled in a pot on a stove. The temperature of the water stayed at 100°C during the entire time that the water was boiling.

Answers

Answer:

The temperature of the water stayed at 100^(0) C because the temperature of a pure water does not increase at its boiling point, 100^(0) C. This is due to latent heat of vaporisation.

Explanation:

During a change of state of a substance, the temperature does not change due to latent heat of the substance. Latent heat is the amount of heat required to convert a unit mass of a substance from one state to another without a change in its temperature. There are two types of latent heat, latent heat of fusion anf latent heat of vaporisation.

So during the experiment, the water got to its boiling point and continues to boil at this constant temperature until it would change completely to steam at that temperature. After the conversion process, the temperature begins to increase.

The latent heat of vaporisation came into action during the process of boiling the water at constant temperature. That's why the temperature of the water did not increase even after reaching its boiling point (100^(0) C ).

Answer:

c,interpretation of the data

Explanation:

A good scientific explanation needs to be based on both data collected in an investigation and on the ability to interpret what the data means.

Normally, adding heat energy increases the temperature of a substance. However, during a phase change, the temperature of the substance stays constant. This happens because the heat energy is being used to change the phase of the matter instead of the temperature.

Answers

a solvent is what is doing the dissolving. so in this case the water would be your solvent because it is dissolving the salt. does that make sense?

Students are completing a table about a particular subatomic particle that helps make up an atom.A 3-column table with 2 rows. The first row has entries Mass (a m u), location, charge. The second row has entries 1/2,000, nothing, has a charge.

What best explains how they should complete the table?

with “Inside the nucleus,” because the particle is a proton
with “Inside the nucleus,” because the particle is a neutron
with “Outside of the nucleus,” because the particle is a proton
with “Outside of the nucleus,” because the particle is an electron

Answers

Answer:

with “Outside of the nucleus,” because the particle is an electron

Explanation:

The table is best completed with “Outside of the nucleus,” because the particle is an electron.

The particle being described is an electron.

Electrons are negatively charged particles with a mass that is about (1)/(2000) of protons and neutrons

Mass(a.m.u)                         location                              charge

      (1)/(2000)                        outside of the nucleus                   negative charge

Electrons orbits round the nucleus in distinct energy levels.

Final answer:

The subatomic particle described in the table is an electron, which is found outside of the nucleus of an atom.

Explanation:

The particle described in the table has a mass of 1/2,000 atomic mass units (a.m.u) and carries a charge. Based on this information, we can conclude that the particle being described is an electron. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom, meaning they are found outside of the nucleus. Therefore, the correct entry for the location column in the table should be Outside of the nucleus.
