Test Review Questions and Electrical Conduction in Axons

Test Review Questions and Electrical Conduction in Axons. 17 February 2012. Voltage Clamp: Vm is stepped to +100mV, Na+ flows outward. Why?. At 100mV, there is more Na inside the cell than outside At 100mV, Na+ ions flow down their electrochemical gradient

Conduction

Transfer of heat Heat is a form of energy. It always flows from one place to another, that is from hot to cold places. Heat flows in 3 ways: 1 ) Conduction 2 ) Convection 3 ) Radiation Heat can move through a solid, liquid, gas or vacuum. Conduction.

Conduction

Newton’s cradle helps to visualize conduction. One ball strikes the rest, and most of the kinetic energy is transferred to one ball on the end. Why is conduction slower in gases than in liquids or solids? Conduction is the transfer of thermal energy with no overall transfer of matter.

CONDUCTION

CONDUCTION. Conduction. Kinetic Energy: Kinetic energy is energy of motion. When an object moves fast, it has lots of kinetic energy . Kinetic Energy. Heat: Heat is a form of Kinetic (motion) energy. For example, molecules of hot air move faster than molecules of cold air. . HEAT.
