Average surface temperature
Gravitational potential energy depends on the difference of height. If the length of the ramp is changed, but the endpoints have the same difference in height, there won't be any change in gravitational potential energy. If, on the other hand, the change is done in a way that the height does change, then gravitational potential energy will also change.

Any force causes acceleration i.e. change in velocity.
The potential energy of the molecules change during a reaction.

The potential evapotranspiration concept was first introduced in the late 1940s and 50s by Penman and it is defined as " the amount of water transpired in a given time by a short green crop , completely shading the ground , of uniform height and with adequate water status in the soil profile ". Note that in the definition of potential evapotranspiration , the evapotranspiration rate is not related to a specific crop .
during summer when temperatures are higher.
precipitation and potential evapotranspiration
Climate ratio is used to describe the moisture side of climate. It compares the precipitation (P) with the potential evapotranspiration (Ep) for a region. One way to do this is to express the relationship between them as a ratio using the formula: Climate ratio = P / Ep When the potential evaporation is greater than yearly precipitation, this ratio is less than 1. When precipitation is greater than evapotranspiration, the ratio is greater than 1. P: precipitation (in mm) or the amount of moisture available for evapotranspiration, evapotranspiration is the combined process of evaporation and plant respiration. Ep: potential evapotranspiration (in mm) or the amount of moisture needed for evapotranspiration. This value increases as temperature and plant life increase. The climate ratios are used to determine climate type: P/Ep: Less than 0.4: arid climate 0.4 - 0.8: semiarid climate 0.8 - 1.2: subhumid climate Greater than 1.2: humid climate Source: NOAA

The Climatic Water Balance (CWB) results from the Precipitation (actual) minus Evapotranspiration (potential) Climatic Water Balance is actual Precipitation minus potential Evapotranspiration CWB=P-PET Exp: PET= 16.09 mm/month P= 46 mm/month CWB=46-16.09 =29.91 mm/month
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
In The Online World It Says That, "They are usually identified by having a low precipitation to potential evapotranspiration (P/PET) ratio."
