Which of the following statements properly describe the first law of thermodynamics: note: you can select more than one alternative select one or more:
a. energy cannot be created or destroyed

b. energy can be changed from one form to another form of energy

c. energy cannot be changed between forms without a loss of usable energy

d. energy to do work decreases as energy changes from one form of energy to another

a and b

Explanation:

The first law of thermodynamics says that energy cannot be created or destroyed. Real world processes usually involve the change of energy from one form to another. For instance when a ball that bounces until it stops, it has changed its kinetic energy for caloric energy that resulted in heating the ball and the floor.

c and d options refer to the second law of thermodynamics

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
