Which is the correct sequence of transferring heat through convection?
1. As a result, the heated part becomes less dense or lighter.
2 The colder air above us is denser and heavier so it goes
down and pushes the hot air upward.
3 The cold air is pushed upward by colder heavier air above. In
this way, the entire liquid or gas becomes evenly heated.
4 When liquid or gas is heated the molecules of the heated part
move faster and faster away from each other.​

the formula would be mgso4

mgso[subscript]4

first one is the correct answer

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
