According to the first law of thermodynamics, the amount of work done by a heat engine equals the amount of a. work done on the engine. b. waste heat it produces. c. thermal energy added to the engine minus the waste heat. d. thermal energy added to the engine plus the waste heat.

B is the correct answer to this problem

The correct answer is option C.

Explanation:

The first law: thermodynamics:

Q = heat added to the system

w = work done by the system

= Internal energy

The work done by the system is equal to the difference of energy added to the system from the internal energy.This internal energy of the system is the energy which is left unused and given out to the surrounding by the heat engine in the form of thermal energy.

yes it is balanced

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
