If you fill up a balloon with a small amount of air, then set it in direct sunlight, you will see that the balloon expands. This expansion is due to an increase in volume, which results from an increase in the temperature of the air in the balloon. This increase in temperature increases the ______________ of the gas, which results in the gas particles moving faster and colliding more often with the wall of the container. These collisions are what increase the pressure of the gas on the balloon, and ultimately cause the balloon to stretch out. A) moles B) spin energy C) kinetic energy D) potential energy

Answer:

c) kinetic energy

Step-by-step explanation:

the kinetic energy of an object is the energy that it possesses due to its motion. the sun increases the temperature of the particles thus forces them to move faster and collide more which results in an increase in kinetic energy this increase causes the balloon to expand.

Answer:

c) Kinetic energy

Step-by-step explanation:

By kinetic mole theory of gas an equation is derived saying


PV=(1)/(3) nRT

and by ideal gas equation we know,


PV = nRT

By combining these equations we get,


(1)/(3)NmC^(2)  = NkT

And that equation can be rearranged as,


(1)/(2)mC^(2)  = (3)/(2)kT

So we find that ,


(1)/(2)mC^(2) = Kinetic energy of a gas molecule.

So as temperature increase kinetic energy of molecules increase.

Please consider that : C² = root mean square velocity

All other symbols in usual notation.

Although ideal gas equations cannot be directly applied to real gases, the behavior of real gases is similar but not as exactly according to the ideal gas equations.
