Answer:
Explanation:
1. Force between two charged ions: Electrical force
Electrical force of attraction exists between two charged ions due to constant flow of electrons occuring within their field of influence.
2. Ion made of two or more atoms of different elements
: Polyatomic ion
A polyatomic ion is made up of two or more different elements. Most radicals forms polyatomic ion e.g SO₄²⁻
3. Compound whose atoms form bonds by transferring electrons
: Ionic compound
Ionic compounds forms by the transfer of electrons from a less electronegativbe atom to a more electronegative one. This is in a bid for the atoms to achieve stability.
4. Smooth solid formed by repeating patterns of ions, atoms, or molecules
: Crystal
A crystal is a unit of an atom which is made up of definite repeating patterns over a long range.
5. Chemical bond formed when electrons are transferred: Ionic bonds
The bonds resulting from the transfer of electrons between two atoms is an ionic bond. An example is that between Na⁺ ions and Cl⁻ ioin in NaCl
Since cells are hard to see the microscope helped them see. scientist were able to actually see cells in tissues placed under the microscope.
Answer:
The differences in atmospheric pressure generate winds.
Explanation:
At the Equator, the sun warms the water and land more than it does the rest of the world. Warm equatorial air rises higher into the atmospher and migrates towards the poles. The complex relationships between fronts cause different types of winds and weather patterns.
I hope this helps :)
Answer:
From hot tea to the ice cube
From the warm coffee to my cold hands
From the hot sand to my feet
Explanation:
Heat always travels from a hot object to a colder object, until equilibrium is reached and the objects are at the same temperature.
