Answer:
D. THEY HAVE THE SAME NUMBER OF PROTONS AND ELECTRONS BUT DIFFERENT NUMBERS OF NEUTRONS.
Explanation:
Isotopy is the phenomenon that explains the various variants of an element having different number of neutrons but the same number of protons and electrons.
Isotopes are variants of a particular chemical element that possesses the same number of proton or atomic number but different mass number. The atomic number of an element is the number of protons and electrons contained by the element while the mass number is the sum total of the number of protons and neutrons in the nucleus of the elements.
Examples of isotopes are the hydrogen atom, chlorine element and so on.
Hydrogen has three isotopes which are hydrogen H, Deuterium and Tritium. Chlorine has two isotopes which are chlorine 35 and chlorine 37.
So the true options about isotopes is that they possess the same number of protons and electrons but different numbers of neutrins.
Answer:
One object could have more particles and greater total kinetic energy
Explanation:
The higher the temperature the more the particles. So, when we have high temperature, there is more particles interacting.
Temperature can simply be defined or gotten by taking the average of of the kinetic energy of the particles in the object that is the keywords here are TAKING THE AVERAGE KINETIC ENERGY
Thermal energy is the energy that can be gotten from adding up all the total kinetic energy of the particles in the object. So, the keywords here are; ADDING UP THE TOTAL KINETIC ENERGIES.
So, when two particles of the same temperature have the different thermal energy it means that One object could have more particles and thus having greater total kinetic energy.
Answer:
A) Devices that transfer kinetic energy have a source of power that is in motion
Kinetic energy is the energy in motion, as such, a device that transfers kinetic energy transfers the energy the power source has into other energy forms
B) Kerosene does not easily cold start like diesel which can burn after compression
C) The first law of thermodynamics states that energy is conserved and it can neither be created nor destroyed, but can be changed from one form to another.
Therefore, when energy is not available in a given location or body, it cannot be obtained from that body or location
