Question 4 energy conversion is: o a measure of energy used for delivering a given service. is the ratio between the useful output and input of an energy conversion process. o is related to any reduction in the amount of energy consumed in a process or system. it is any behavior that results in energy transformation.

It is any behavior that results in energy transformation.

Explanation:

a. Energy efficiency is a measure of energy used for delivering a given service.  

b. Energy conversion efficiency is the ratio between the useful output and input of an energy conversion process.

c. Efficient energy use is related to any reduction in the amount of energy consumed in a process or system.

d.  Energy conversion is is any behavior that results in energy transformation.

According to law of conservation of energy, energy remains conserved. It only transforms from one form to another. For example: When food is oxidized, the chemical energy stored in the bonds of food converts to kinetic energy which is the energy possessed by an object by virtue of motion.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
