Answer:
True
Explanation:
Every material in made up of intensive or extensive property. Intensive property of a system does not depend on the system size or the amount of material in the system. But extensive property on the other hand depends on the amount of material present in the system.
Examples of intensive properties include temperature, density, vapor pressure and viscosity.
Assuming that there is some residual liquid left after equilibrium is reached, no matter how much liquid is present, at any given temperature, the vapor pressure will be the same because it is an intensive property.
changes in density
Explanation:
The global thermohaline (conveyor belt) circulation is caused by changes in global ocean density.
The ocean water density is determined by the temperature and salt content of the ocean (thermo - heat and haline - salt).
- Surface current drives warm and less water away for the equator towards the poles.
- At the poles they become cold and very dense sinking to the bottom and moving towards the equator back.
- It is also called the ocean conveyor belt

Answer:
<u>A. Magnet has a north pole and south pole.</u>
Explanation:
- A magnet has a north and south pole
- Magnets attract paper clips due to the metals present
- Magnetic fields are not visible
- North pole and south pole attract each other
Only the first statement is correct, the answer is (A).
Aurous is a cation of gold. Gold takes the name "aurum" (Au) with atomic number of 79. In its purest form, the element is bright, slightly yellow, soft, ductile, and malleable. The charge of aurous is +1. Sulfide, on the other hand, has a charge of -2.
Hence, the chemical formula of the compound is Au₂S and its systematic name is gold (I) sulfide.
