An iron has an aluminium plate with a mass of 1.5 kg. Calculate the thermal energy stored in the plate
when the temperature rises from 20°C to 200°C. The
specific heat capacity of aluminium is 913 J/kg°C.

What is the earliest point in the universe that we can observe? why can’t we see back further than this?

Avalue that describes how heavy an object is and is related to the force of gravity is

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.
