The correct answer is option B: More. Silver has a higher thermal conductivity than copper. Thermal conductivity refers to a material’s ability to conduct heat. Silver, with a thermal conductivity of approximately 429 watts per meter Kelvin (W/mK), surpasses copper’s thermal conductivity of about 401 W/mK. This characteristic makes silver an excellent conductor of heat, often utilized in applications where efficient heat transfer is crucial, such as in electronics and thermal interface materials. Copper is also a good conductor but slightly less efficient than silver. Therefore, the correct answer is option B: more. Silver’s superior thermal conductivity makes it a preferred choice in various industries where heat management is essential for optimal performance and efficiency.

The correct answer is [B] Mercury. The best conductor of heat among the options provided is mercury. Mercury is a metal with high thermal conductivity, meaning it can efficiently transfer heat. In contrast, water, wood, and leather are poor conductors of heat. Water has a relatively low thermal conductivity due to its molecular structure, while wood and leather are insulators and do not conduct heat well. Mercury, being a metal, has free-moving electrons that can easily transfer thermal energy throughout its structure, making it an excellent conductor of heat.
The correct answer is [A] Conduction. The method of heat transmission in which the particles of the medium do not move is conduction.

The correct answer is [A] Conduction. The method of heat transmission in which the particles of the medium do not move is conduction. Conduction involves the transfer of heat through direct contact between particles in a material medium. When one part of a solid object is heated, thermal energy is transferred from the hotter region to the cooler region through collisions between adjacent particles. However, the particles themselves do not undergo significant movement from their positions; rather, it is the energy that is transferred through the material. In contrast, convection involves the movement of fluid particles carrying heat energy, while radiation involves the transfer of heat through electromagnetic waves.
The correct answer is [C] Radiation. In the method of heat transfer known as radiation, a medium is not necessary. Radiation involves the transfer of heat energy through electromagnetic waves, such as light and infrared radiation. Unlike conduction and convection, which require a material medium, raRead more
The correct answer is [C] Radiation. In the method of heat transfer known as radiation, a medium is not necessary. Radiation involves the transfer of heat energy through electromagnetic waves, such as light and infrared radiation. Unlike conduction and convection, which require a material medium, radiation can occur even in a vacuum, such as outer space. This is because electromagnetic waves can propagate through empty space without the need for any material substance to carry them. Therefore, radiation is the only method of heat transfer where a medium is not required for the transmission of heat energy. Conduction involves the transfer of heat through direct contact between particles in a material medium, while convection involves the transfer of heat through the movement of fluid particles within a medium. However, radiation can occur independently of any material medium, making it unique among the three methods.
The correct answer is [B] Radiation. The Sun's heat reaches the Earth primarily through radiation. Radiation is the transfer of heat energy through electromagnetic waves, such as light and infrared radiation, that travel through the vacuum of space. These electromagnetic waves carry energy from theRead more
The correct answer is [B] Radiation. The Sun’s heat reaches the Earth primarily through radiation. Radiation is the transfer of heat energy through electromagnetic waves, such as light and infrared radiation, that travel through the vacuum of space. These electromagnetic waves carry energy from the Sun and warm the Earth’s surface when they are absorbed. Unlike convection, which involves the transfer of heat through the movement of fluids, and condensation, which is a phase change process, radiation does not require a medium to propagate. Heat exchange is a broad term that can encompass various methods of transferring heat, including conduction, convection, and radiation, but it is not specific to the transmission of heat from the Sun to the Earth.
