Carmen is heating some water and trying to measure the temperature of water using a Celsius thermometer. Which measurement can she expect once the water begins to boil?32°C
100° C
212°C
373°C

Answers

Answer 1

Answer:

100° Cshe can expect once the water begins to boil.

Option: B

Explanation:

The boiling point for water at 1 pressure atmosphere of sea level is 212 ° F or 100 ° C. That value isn't a fixed. Water's boiling point is dependent on the ambient pressure, which varies based on elevation. At a lower temperature, water boils as one gains altitude like getting higher on a hill, and boils at a higher temperature if one increases the atmospheric pressure of returning to or below sea level.

It also relies upon the water's purity. Water containing contaminants like salted water boils at a level higher than pure water. This effect is called acceleration of the boiling point and is one of the material's colligative features.

PLZ HURRY!!WILL BE FRIEND FOREVER!!1. When an object is burning, two atoms of oxygen (in the air) combine with one atom of carbon (from the substance burning). This forms carbon dioxide gas. Explain how the law of conservation of matter applies to this reaction.

Answers

Answer:

When you burn 1 carbon, 2 atoms of oxygen will react with the carbon which forms carbon dioxide with 3 atoms. The law conservation applies since it states that mass can never be created nor destroyed. In simple terms, the amount used for the reaction should be the same amount produced.

Why do faults often occur along plate boundaries?

Answers

Earthquakes can also occur far from the edges of plates, along faults. Faults are cracks in the earth where sections of a plate (or two plates) are moving in different directions. Faults are caused by all that bumping and sliding the plates do. They are more common near the edges of the plates.

Hi :) what’s the difference between conduction in metals & non-metals ? I know it’s the free electron diffusion thingy but I really don’t understand it at all. anyone able to help? Thank you!

Answers

The difference between metal and non-metal in terms of condition is explained below.

Explanation:

In metals, conduction occurs due to the aggregation of vibrations of molecules and free-electron distribution. While in non-metals, the mechanism for conduction is only atomic or molecular vibrations.
Apart from free electrons, there are phonons in metals as well as non-metals. Non-metals hold a confined amount of thermal conductivity only due to Phonons and Lattice vibrations.
Concerning atomic vibration in a solid thing (non-metals mainly), it is easier to know if one receives the fact that atoms are almost floating adjacent to one another depending on the covalent bonds between them.
When a metal is heated the electrons quickly respond to the heat and transfer it to the nearby atom or solid touching it. As non-metals don't possess free electrons, the heat transfer happens due to phonons (the excited state of the lattice structure vibrating uniformly).
In metals, this rarely plays a role as the electrons transfer most of the heat efficiently.

What must occur before clouds can form?

Answers

The three conditions that must occur before clouds can form Sufficient water vapor must be present in the air. Water vapor is the invisible gas form of water. It is all around us, even in dry air.

What are the other conditions?

A surface for water vapor to condense on is needed. This is called a cloud condensation nuclei (CCN). CCN can be anything from dust particles to salt crystals.

The air must cool to its dew point. The dew point is the temperature at which the air is saturated with water vapor. When the air reaches its dew point, the water vapor will condense on CCN and form clouds.

In addition to these three conditions, there are other factors that can affect cloud formation, such as the wind and the amount of sunlight.
