Chapter 1: Problem 48

Which form of energy transfer occurs most readily in a vacuum? 1\. Convection 2\. Conduction 3\. Radiation 4\. Two of the above

Short Answer

Expert verified
Radiation is the form of energy transfer that occurs most readily in a vacuum, as it does not require a medium (like a fluid or solid substance) to transfer heat. Convection and conduction cannot occur in a vacuum since they rely on particles or substances for heat transfer. The answer is 3. Radiation.

Step by step solution

01

Understanding Convection

Convection is the transfer of heat within a fluid (gas or liquid) due to the movement of the fluid itself. In a vacuum, there are no particles to act as a fluid medium that can transfer heat through convection. Therefore, convection cannot occur in a vacuum.
02

Understanding Conduction

Conduction is the transfer of heat between substances in direct contact with each other due to the movement of molecules and atoms within the substances. In a vacuum, there are no particles or substances in direct contact with each other for heat transfer to occur through conduction. Therefore, conduction cannot occur in a vacuum.
03

Understanding Radiation

Radiation is the transfer of energy as electromagnetic waves through space. It does not require a medium (like a fluid or solid substance) to transfer heat. Radiation can happen in a vacuum since it does not rely on particles or substances to transfer energy. Examples of radiative energy transfer can be observed from the sun's energy reaching the Earth through the vacuum of space.
04

Conclusion

Comparing the three forms of energy transfer, we can conclude that radiation occurs most readily in a vacuum, as convection and conduction require a medium to transfer energy, whereas radiation does not. Therefore, the answer is: 3. Radiation

When an electron falls from \(\mathrm{n}=3\) to \(\mathrm{n}=2\) in a hydrogen atom, what is the value of the energy released, given that \(A\) is the energy needed to remove an electron from the ground state of a hydrogen atom to an infinite distance from the atom? 1\. \(0.14 \mathrm{~A}\) 2\. \(0.17 \mathrm{~A}\) 3\. \(1.00 \mathrm{~A}\) 4\. \(5.00 \mathrm{~A}\)

An apparatus is set up to measure the standard potential of a chemical reaction. When the apparatus is in operation, which of the following correctly describes of the movement of electrons? 1\. Through the ammeter to the anode 2\. Through the ammeter to the cathode 3\. Through the voltmeter to the anode 4\. Through the voltmeter to the cathode

Why does an incandescent light have a longer life when an inert gas is used rather than a vacuum? 1\. The filament vaporizes more slowly. 2\. Heat is removed from the filament. 3\. The bulb is less likely to implode when subjected to vibration. 4\. The gas directly absorbs energy from the electrons in the filament.

6\. What is the strongest intermolecular interaction between \(\mathrm{H}_2 \mathrm{O}\) and \(\mathrm{CH}_3 \mathrm{OH}\) molecules? 1\. Dipole-dipole 2\. Dipole-induced dipole 3\. H-bonding 4\. Dispersion

Gas \(\mathrm{A}\) is at \(30{ }^{\circ} \mathrm{C}\) and gas \(\mathrm{B}\) is at \(20^{\circ} \mathrm{C}\). Both gases are at 1 atmosphere. What is the ratio of the volume of 1 mole of gas A to 1 mole of gas B? 1\. \(1: 1\) 2\. \(2: 3\) 3\. \(3: 2\) 4\. \(303: 293\)
