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

c) Kinetic energy

Explanation:

By kinetic mole theory of gas an equation is derived saying

and by ideal gas equation we know,

By combining these equations we get,

And that equation can be rearranged as,

So we find that ,

= 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.

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.
