Do objects float better in hot or cold water? Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. Hot water is less dense and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water. […]

It also plays a key role in maintaining blood pressure and controls cardiac contractions. What human body system depends on the sodium potassium pump? nervous system Why […]
Why does electronegativity increase as you go across a period?
Why does electronegativity increase as you go across a period? It is no wonder the electron pair gets dragged so far towards the chlorine that ions are formed. Electronegativity increases across a period because the number of charges on the nucleus increases. That attracts the bonding pair of electrons more strongly. How does electronegativity vary […]
What is the magnitude of the force on an electron between the plates?
What is the magnitude of the force on an electron between the plates? The electron accelerates toward the upper plate. The electric field strength between the plates is 4.8 X 10 newtons per coulomb. Why does the charge change as you move the plates? Moving the plates further apart decreases the capacitance, also reducing the […]

What happens when a neutron hits a control rod?
What happens when a neutron hits a control rod? If the neutron hits another nucleus, the reaction continues. If the nucleus hits a control rod it is absorbed and no further reaction takes place. 9) Compare the chain reaction that occurs when the control rods are inserted further into the reactor versus when they are […]
