The most complex processing of sensory information occurs in the cerebral cortex

In a good thermo flask the main cause of heat loss is

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
