When the electrostatic force overcomes the force in at least part of the nucleus it is called radioactive decay
Atoms with certain characteristics are radioactive Which is least likely to be radioactive
all atoms with an atomic number under 40
Cesium-133 has an atomic number of 55 It has neutrons
The strong nuclear force acts over a smaller distance than the electrostatic force
Entropy is the amount of heat a system releases
The first law of thermodynamics which is closely related to the law of conservation of energy states that
energy can be transformed in different ways but can never be
created or destroyed.
Which item requires the least energy to increase its temperature lounge chair sand or water Explain your answer in terms of this item's specific heat
Sand needs least energy to increase the temperature as its
specific heat is very low compared to that of water. Water needs
more energy to increase its temperature as its specific heat
capacity is higher.
Which of the following are formulations of the second law of thermodynamics
I’m a nuclear reaction which of the following must be conserved
Charge
The count of nucleons
