Which materials do not allow heat to pass through them easily? Then there are materials called “insulators” that do not allow energy to pass through easily. These materials include plastic, cork, wood, Styrofoam, and rubber. Thermal insulators are thus good at maintaining a consistent level of heat — whether hot or cold. What’s the best […]

A lower percent yield might signal that you mis-measured a reactant or spilled a portion […]
Why does convection work more quickly than conduction?
Why does convection work more quickly than conduction? In convection there is actual movement of fluid particles for heat transfer whereas in conduction, the particles only vibrate at their position and transfer heat. Due to this kinetic energy transfer in convection is faster than conduction and hence convection is the more efficient way of heat […]
