$Assertion :$ It is hotter over the top of a fire than at the same distance of the sides.
$Reason :$ Air surrounding the fire conducts more heat upwards.
A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
C
If the Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

C
If the Assertion is correct but Reason is incorrect.
c It is hotter over the top of a fire. It is because of convection current established over the fire. As air warms up, its density decreases as a result of which it goes up and makes upper layer of air hot. The Reason is incorrect.

Two spheres of different materials one with double the radius and one-fourth wall thickness of the other, are filled with ice. If the time taken for complete melting ice in the large radius one is $25$ minutes and that for smaller one is $16$ minutes, the ratio of thermal conductivities of the materials of larger sphere to the smaller sphere is
A beaker full of hot water is kept in a room. If it cools from $80^{\circ} C$ to $75^{\circ} C$ in $t_1$, minutes, from $75^{\circ} C$ to $70^{\circ} C$ in $t_2$ minutes and from $70^{\circ} C$ to $65^{\circ} C$ in $t_3$ minutes, then
Which of the following graphs correctly represents the relation between ln $E$ and ln $T$ where $E$ is the amount of radiation emitted per unit time from unit area of a body and $T$ is the absolute temperature
Six wire each of cross-sectional area $A$ and length $l$ are combined as shown in the figure. The thermal conductivities of copper and iron are $K_1$ and $K_2$ respectively. The equivalent thermal resistance between points $A$ and $C$ is :-
The maximum wavelength of radiation emitted at $2000\;K$is $4\mu m$. What will be the maximum wavelength of radiation emitted at $2400\,K$ is ...... $\mu m$
Two circular discs $A$ and $B$ with equal radii and equal mass are blackened. They are heated to same temperature and are cooled under identical conditions.What inference do you draw from their cooling curves ?
