Question

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

Answer 1

The given statement for temperature and convection is False.

Step-by-step 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)`
