Which of the following are methods of
- a.
Convection - b.
Conduction - c. Temperature
- d.
Radiation - e. Potential energy
Choose the correct option.
Answer to Problem 1RQ
The correct options are “a. Convection, b. Conduction, d. Radiation”.
Explanation of Solution
Convection is the moment of hot molecules of water or air from a region of hot reservoir to a region of cold reservoir.
Conduction is the flow of heat from one solid medium to another solid medium when placed in contact.
Temperature is the degree of heat present in an object. It is the amount of hotness or coldness of the body.
Radiation is the emission of heat energy in the forms of a wave. This type of heat transfer is similar to light.
Potential energy is the amount of energy required to bring a unit positive charge from infinity to that point.
Therefore, the processes by which heat is transferred are convection, conduction, and radiation. Therefore, options a, b, and d are correct.
The temperature and potential energy cannot perform heat transfer, therefore, option c and e are incorrect.
Conclusion:
Hence, the correct options are “a. Convection, b. Conduction, d. Radiation”.

Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…arrow_forward
