How does the temperature of absolute zero relate to the kinetic energy of a substance?

Absolute zero is the point where where all molecules have no kinetic energy. It is a theoretical value (it has never been reached). The Kelvin temperature scale is based on absolute zero being the lowest possible temperature that could theoretically be reached.

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.

The correct answer is c. hope this
