Q. Assertion [A]: Convection currents leads to the movement of fluids from one place to another in a cyclical manner.

Reason [R]: The cyclical movement of fluids is a result of temperature and density differences of the fluid in the Earth's mantle and core.

Read the following statements about convection currents and select the option that is true.

Q. It is given that rate of heat transfer in convection is directly proportional to area of plate across which fluid flows

A

,density of fluid (

ρ

), velocity of flow (

V

),temperature difference (

t

) with proportionality constant of 2 units.Also fluid is flowing across edge to edge on a square plate of side length of 0.1 unit with density of fluid is 10 units and velocity of 2 units. Then what will be the rate of heat conducted through the plate if temperature difference between plate and fluid is unity?(assume that all

u n i t s

are in international standards)

Q. A spherical body having radius

0.5 m

is transfering heat to its surrounding through convection. Find the temperature difference between surrounding and the body surface, if the rate of heat transfer is
