The temperature of the liquid in a container decreases as the liquid evaporates. use kinetic theory to explain why.

Orange juice has a lower or higher viscosity than chocolate syrup

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

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
