An interval of 1 degree Celsius is equal to 1 Kelvin
Explanation:
There are different scales used for measuring temperatures. The most common ones are:
- Celsius scale: it is set by the following convention: the zero in this scale is placed at the freezing temperature of the water, while the 100 degrees is placed in corresponding to the boiling point of water. The the scale is divided into 100 equal intervals between these two points. Temperatures in this scale are indicated with the Celsius degree (.
- Kelvin scale: it is set such that the absolute zero (the temperature at which particles in matter stop to have any motion) is placed at zero in this scale. A difference of 1 degree in this scale is equal to 1 degree Celsius. Temperatures in this scale are indicated with the Kelvin (K).
The conversion between the two temperatures is:
So for example, the absolute zero () corresponds to
in the Celsius scale. However, intervals between two temperatures are measured in the same way in the two scales: therefore, an interval of 1 degree in the Celsius scale is equal to an interval of 1 Kelvin in the Kelvin scale.

<u>Elastic Potential Energy </u>
We find objects like springs that hold potential energy when stretched and they have the capacity to release it when left return to its equilibrium position. The elastic potential energy of a spring of constant k when is stretched a distance x is
The spring constant can be obtained if we know the force N needed to stretch the spring a distance x, by using the Hook's Law
The question provides the information that a force of F = 25 N stretches a spring x= 5 cm = 0.05 m. Using the formula F=kx we can compute the value of k.
The potential energy of the spring in the compressed position (assumed 5 cm as well) if
