c are based on the following description a sample of gas is kept at STP in a 6.0 container with a moveable piston was compressed into 3.0 L at constant temperature. 1).which parameter of the gas remained the same? 2) what was the temperature of the gas? 3) what was the final pressure of the gas? a) 1 atm b) 0.5 atm c) 2 atm. 3) what is the proper unit for pressure?

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
