It’s organized by the atomic number which is the protons so the answer is A although they can be organized through groups and periods if valance electrons are included
Answer:
B. convection because warm air rises and cool air sinks.
Explanation:
The processes that enables birds to fly to higher altitudes without flapping their winds while riding air thermals is called convection.
Convection is one of the forms of heat transfer usually found in gases and liquids.
- In convection density differences due to temperature changes causes the circulation.
- Warm air is less dense and it is hotter.
- It rises up from the surface where it is warmed
- Cold air sinks to replace the warm air. Cold air form when the air loses its energy to the surrounding.
- By virtue of this, birds are able to take advantage of it for their flight.
Protons and neutrons exist within the neucleus, while electrons do not.
Explanation:
mass of an object affect the density and object if the the volume is keep constant.
here we can explain by using the example.
if the mass of an object is 30kg. and volume is 2m3
then density pf given substance is become 15kg/m3
again,
if the mass of the is 40kg/m3 and volume is same
then density is become 20kg/m3 (formula=kg/m3)
here above density and below density is becime different by changing the mass of an object and affect the density and objecy although volume is kept constant or same
