Question

an iron ball at 40c is dropped in a mug containing water at 40c. the heat will? and why?

Answer 1

HEY!!

when an iron ball at 40 °C is dropped in a mug containing water at 40 °C there will be no transfer of heat between the two. This is because the iron ball and the water in the mug are in thermal equilibrium.

 

Answer 2

$\huge\mathfrak{A{\underline{\underline{\textbf{\red{nswer :}}}}}}$



As the temperature of both iron and water is is same i.e. 40°C... And because of same temperature there will be no transfer of heat... 

But it can flow from higher temperature to lower temperature.. i.e. diffusion because in diffusion gas/heat flow from high concentration to lower concentration... 

So, heat flows from hotter end to it's cooler end means from hot to cold...
