Differentiate clearly between thermal conduction,thermal convection,and thermal radiation.
(N/A) Thermal energy can be transferred through three distinct mechanisms:
$1$. Thermal Conduction: Heat transfer in solids where particles vibrate about their mean positions without net displacement. It does not require gravity and does not involve the formation of currents.
$2$. Thermal Convection: Heat transfer in fluids (liquids and gases) where particles physically move from one region to another,carrying thermal energy. This process requires gravity and leads to the formation of convection currents.
$3$. Thermal Radiation: Heat transfer in the form of electromagnetic waves (specifically infrared radiation). It does not require any material medium for propagation and can occur in a vacuum.

$(a)$ a body with large reflectivity is a poor emitter.
$(b)$ a brass tumbler feels much colder than a wooden tray on a chilly day.
$(c)$ an optical pyrometer (for measuring high temperatures) calibrated for an ideal black body radiation gives too low a value for the temperature of a red hot iron piece in the open,but gives a correct value for the temperature when the same piece is in the furnace.
$(d)$ the earth without its atmosphere would be inhospitably cold.
$(e)$ heating systems based on circulation of steam are more efficient in warming a building than those based on circulation of hot water.

The points $A$ and $B$ are maintained at different temperatures. The ratio of the heat transferred through a cross-section of the semi-circular rod to the heat transferred through a cross-section of the straight rod in a given time is

View SolutionThe power radiated by a black body is $P$ and it radiates maximum energy around the wavelength $\lambda_0$. Now the temperature of the black body is changed so that it radiates maximum energy around wavelength $\left(\frac{\lambda_0}{2}\right)$. The power radiated by it will now increase by a factor of
If $120 \ J$ of thermal energy is incident on an area of $3 \ m^2$,the amount of heat transmitted is $12 \ J$,and the coefficient of absorption is $0.6$,then the amount of heat reflected is: (in $J$)
