How can you use the movement of molecules to determine when a phase change has occurred?
Answer:
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.

Areas with mountains are warmer than other areas at the same latitude.
Answer:
Places at the same latitude may have very different climates if one is on a coast and one is inland. On the coast, the climate is influenced by warm moist air from the ocean. A coastal climate is usually mild. ... Farther inland, the climate is influenced by cold or hot air from the land.
Explanation:
Hopefully its correct!
The statement 'areas with mountains are warmer than other areas at the same latitude' is FALSE.
At high altitudes, the temperature is colder than in areas closer to the sea level.
At higher altitudes, there are fewer air molecules in a specific surface area than in the same area at lower levels. Thus, as air rises, the air pressure decreases.
This lower air pressure causes the temperature to be colder at high altitudes than at sea level.
In conclusion, the statement 'areas with mountains are warmer than other areas at the same latitude' is FALSE.

The strength of the gravitational attraction depends on the mass of the objects involved and on the distance between them. The gravitational force between two objects will be lowest in which of the following situations?
A. Both objects have small masses and are close together.
B. One object has a large mass, and the objects are close together.
C. Both objects have large masses and are close together.
D. Both objects have small masses, and they are far apart.
Why is it important for the path of a circuit to be circular?
Answer:
When the platform rotates, the rotating mass will travel in a circular path due to the force exerted on it by the string (by way of the tension in the spring). Since it is not possible to have an instantaneous readout of this tension force while the platform is rotating, an indirect measurement of this force will be made using the weight of the static mass as shown and explained below.

What happens to the compass needle as you move the compass around?
A.The compass needle always points north
B.The compass needle points in random directions.
C.The compass needle follows the pattern of magnetic field lines
D.THE compass needle's north pole always points to the north pole of the magnet
When the compass needle as you move the compass around, Then the compass needle follows the pattern of magnetic field lines. The correct option is C.
What is the pattern of magnetic field lines?
Magnetic field lines are imaginary lines used to represent the direction and strength of the magnetic field around a magnet or a current-carrying wire. The pattern of magnetic field lines depends on the shape and orientation of the magnet or the wire, as well as the direction and strength of the magnetic field.
The magnetic field lines around a magnet emerge from the north pole and loop back into the south pole in a continuous path. They are always closed loops, meaning they do not begin or end anywhere but instead form a continuous path around the magnet. The magnetic field lines are closer together near the poles of the magnet, indicating a stronger magnetic field in those regions. They become less dense as they move further away from the poles, indicating a weaker magnetic field in those regions.
Here in the question,
When a compass is moved around, the compass needle aligns itself with the direction of the magnetic field lines in the vicinity. Magnetic field lines are the paths that a small compass would follow if it were placed at various points around a magnet. They indicate the direction of the magnetic field at each point.
The compass needle has a north-seeking pole and a south-seeking pole. The north-seeking pole of the compass needle aligns itself with the direction of the magnetic field lines, which are oriented from the north pole of a magnet to the south pole. This means that the north-seeking pole of the compass needle will point towards the south pole of a magnet, while the south-seeking pole of the compass needle will point towards the north pole of the magnet.
Therefore, as the compass is moved around a magnet or any other magnetic field, the compass needle will follow the pattern of the magnetic field lines, and the north-seeking pole of the compass needle will always point towards the south pole of the magnet or the magnetic field source.

What is one way that an electric field is different from a magnetic field?
Answer:
The one of the major difference between the magnetic and electric field is that the electric field induces around the static charge particle which is either negative or positive, whereas the magnetic field produces around the poles (i.e., the north and south pole) of the magnet
Explanation:
Difference Between Electric Field And Magnetic Field. Magnetic field is an exerted area around the magnetic force. It is obtained by moving electric charges. The direction of the magnetic field is indicated by lines. While the electric fields are generated around the particles which obtains electric charge.
