If a car's engine gives off 65% thermal energy, what is the maximum efficiency?

Physics
1 answer:
stich3 [128]3 years ago
5 0

Answer:

35%

Explanation:

The car's engine gives off 65% thermal energy

So only 35 % is converted into mechanical energy .

input heat = Q₁ = 100

output heat = Q₂ = 65

Work output = Q₁ - Q₂ = W

W = 100 - 65 = 35

Efficiency = W / Q₁ X 100

= (35/ 100) X 100

= 35%.

Water has a very high specific heat, Why does this make it a very good substance for use in
Alex Ar [27]

Answer:

Water has high specific heat capacity so without a high increase in temperature , water can absorb a large amount of heat.

Explanation:

Water is a very good substance for use in cooling system of automobiles because water has a ridiculously high heat capacity specially its volumetric heat capacity.

 water takes  a tremendous energy  to change the temperature of water and and it gives enormous cooling capacity compared to metals like rapidly absorbing heat energy from the engine.

To cool down the car engine water is used. Water has high specific heat capacity so without a high increase in temperature , water can absorb a large amount of heat.

 Water is efficient heat transfer fluid .

Water offers the thermal conductivity advantages of a liquid with high specific heat capacity and evaporative cooling .

What is a characteristic of weight <br> I need it please answer it
Ann [662]

Answer:

Weight is a consequence of the universal law of gravitation

Explanation:

Weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. Weight is a consequence of the universal law of gravitation: any two objects, because of their masses, attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
