Will give 20 points!! Mr. Telesco has two metal cubes one made of tin and the other made of silver. He heats the tin cube to 80 degrees Celsius and places the silver one in the freezer until it reaches 5 degrees Celsius. He places the cubes in a beaker containing 20 degree Celsius water. The cubes do not touch. Which best describe how the heat will flow in the system? *

1 point

Heat flows from the silver cube into the tin cube.

Heat flows from the silver cube into the water.

Heat flows from the tin cube to the silver cube.

Heat flows from the tin cube into the water.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

the answer is 0.8m.
