There are 40 liters of helium in a balloon at 100 K. If the temperature of the balloon is increased to 200 K, what will the new volume of the balloon
be?

Explanation:

By the Ideal Gas Law, PV = nRT.

Assuming that the pressure inside the balloon remains the same, that means volume is directly proportional to temperature.

40 litres at 100K

=> 80 litres at 200K.

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.
