Explanation:
Conduction:
Heat transfer in the conduction occurs due to movement of molecule or we can say that due to movement of electrons in the two end of same the body. Generally, phenomenon of conduction happens in the case of solid . In conduction heat transfer takes places due to direct contact of two bodies.
Convection:
In convection heat transfer of fluid takes place due to density difference .In simple words we can say that heat transfer occur due to motion of fluid.
Answer:
(d) all of the above
Explanation:
Effect on the density of temperature: If we increase the temperature of any room then particles of the room moves and to and fro and so density is decrease
Effect on the viscosity of temperature : viscosity is inversely proportional to the temperature if we increase the temperature viscosity decreases and if we decrease the temperature viscosity increases.
Effect on the resistance of temperature : For metals if we increase the temperature then resistance increases and for semiconductor if we increase the temperature resistance decreases
So from above discussion all the parameter depends on the temperature so option (d( will be the correct option
Answer:
Space Cushion
Explanation:
Having an adequate Space Cushion provides a driver with the time and space necessary to react to potential and immediate hazards in the driving scene.
