Are gas containing organ injuries attributed to thermal effect?
Primary blast effect
What is the Dimensional formula of thermal resistance?
no
Which has the greater resistance thick wire or a thin of the same length?
The thermal resistance of a wire is proportional to ln(r2/r1), meaning that a thicker wire has a greater thermal resistance.
properties of plastic?
Strength. Weather Resistance. Fire Resistance. Durability. Dimensional Stability. Chemical Resistance. Thermal Resistance. Working Conditions.
What are the drawbacks of pirani gauge?
The Pirani gauge is base on a heating element that is cooled due to the thermal conduction of the measured gas. The heating elements resistance drops as the thermal conduction is increase i.e. more gas results in a drop in resistance. On the other hand less gas results in less conduction increased temperature of the heating element and increased measured resistance. This is a very robust gauge and is suitable for relatively high pressures, down to 10^-4 Torr. Below that you need a different gauge as the low number of gas molecules does not allow any measureable change.
What is thermal risistance?
It is the rate of resistance of a material to heat.
What are some examples of items with low conductivity?
Thermal resistance: diamond Electrical resistance: copper Optical resistance: quartz
What is thermal chemical?
A gas used for thermal heat etc.
What increases the?
The thermal vibration of the atoms in the material increases the resistance of that substance. The resistance is greatly depends on temperature.
What are the sources of resistance to change?
A: There is only one source thermal
What form of energy changes water from liquid to gas?
Thermal Thermal
What is reformed gas?
A lower-thermal-value fuel gas made by pyrolysis and steam decomposition of high-thermal-value natural and refinery gas
