Question

The efficiency of a heat engine if the temperature of the source is 100 degree Celsius and sink is 27 degree Celsius is nearly

Answer 1

Answer:

19.7%

Explanation:

Refer to the material.

Answer 2

The efficiency of a heat engine if the temperature of the source is 100 degree Celsius and sink is 27 degree Celsius is nearly 0.2.

• Energy applies to the fact of the momentum of energy.
• In that case, the well-known factor is that energy is not to be created nor to be destroyed.
• Energy is measured in the standard unit of a joule.
• The energy is to be indifferent they are chemical energy, electrical energy and light energy.
• The energy formula was invented by Albert Einstein.
• Energy is done by the form of motion.
• Energy falls under the scalar quantity.
• Energy is an important factor for all kinds of work.
• Energy is an essential criterion for all kinds of things.
• Without energy, nothing can happen in this world.
• Energy falls in the movement of action and momentum.
• Power is the critical factor for the capacitor and resistance.
• The standard power unit is the watt; sometimes, it is measured in joules.
• Power is nothing but, it is the charge of the electric current.
• It is done between intervals of time.
• The power is the capacity of the work done.

To find :

Celsius is nearly?

Given :

Initial temperature= 100°C =373K

Final temperature=270°C =300K

Solution :

The heat engine efficiency is given by,

η=1- T₂/T₁

Substituting the values we get,

η=1 - 300/373

On solving we get,

η=0.195≈0.2

Therefore, efficiency of a heat engine if the temperature of the source is 100 degree Celsius and sink is 27 degree Celsius is nearly 0.2.
