Carmen is heating some water and trying to measure the temperature of water using a Celsius thermometer. Which measurement can s
andrew-mc [135]

<u>100° C</u> she can expect once the water begins to boil.

<u>Option: B</u>

<u>Explanation:</u>

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.

Why must the electric field be normal to the surface at every point of a charged conductor?
solong [7]
-- If the field were inclined to the surface, then it would have
some component parallel to the surface. 

-- Then, since we're talking about a conductor, the charges
on the object would move in response to that component
of the field, until there was no longer any component of the
field trying to move them.

. What happens to the polarity of an electromagnet when the direction of the current passing through it is reversed?
eduard

Answer:

The polarity of electromagnet also gets reversed when the direction of current is reversed. The current flows from negative terminal to positive terminal in an electromagnet due to the flow of electrons so polarity is also established in the electromagnet. As, the current direction is reversed, the polarity of magnet also gets reversed because the polarity of magnet depends on the direction of the current.
