Using scientific principles describe a device that you could design and test to minimize thermal energy transfer from the cup of cocoa after removing from microwave

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Is there an image with it

The higher the temperature, the increased rate constant for a reaction.(positive linear association)
