Convection is a function of temperature to the fourth power. a)-True b)-False

strojnjashka [21]

Answer:

The given statement for temperature and convection is False.

Explanation:

Convection is not a function of temperature to the fourth power but it depends linearly on temperature. the below equation shows the linear relation of heat transfer due to convection and temperature:

Q = $H_{c}A(T_{hot} - T_{cold} )$

Whereas, radiation is a function of temperature to the fourth power.

The Stefan-Boltzmann law gives the relationship between an object's temperature and the amount of radiation it emits. The law is given by:

$Q=\sigma T^{4}$
