Jenna performed a lab in which she added a constant amount of heat to change ice to liquid water to water vapor. she measured the temperature every minute and graphed the results . the graph was a straight line . are her results reasonable? explain

A scientist cools some water at a constant rate. the graph and table show how the temperature of the water changes with time. CAN SOMEONE ANSWER THIS. ?

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.
