Conduction is a heat transfer method used to remove heat from sensitive electronic seale. -expansion is the amount a unit length of a material lengthens parts F 2 A reference temperature is a known fixed point meeded to define a tenperature 3. The coefficient of - - - or contracts with temperature changes A. area B. linear C. thermocouple D. volumetric 4. is the degree or intensity of heat measured on a definite scale. 5. is the unaided movement of a gas or liquid caused by a pressure difference due to a difference in density within the gas or liquid. A. Conduction B. Induction C. Forced convection D. Natural convection 6. is the lowest temperature possible, where there is no molecular movement and the energy is at a minimum. A. Absolute zero B. Positive zero C. Negative 100 D. Absolute 100 7. Four common are the Fahrenheit, Rankine. Celsius, and Kelvin. A. units of length B constants C. thermocouples D. temperature scales &.

A heat sink is a heat conductor that adds heat to electronic parts by pressure dif- ference 17Explanation / Answer
1. yes,conduction is used to tranfer heat from senitive elecronics parts
2. yes, reference temp is a fixed point to define the scale
3. the degree of expansion of material with temp is called as thermocouple coefficient
4. Kelvin
