How diffusion coefficient depends on temperature?
The diffusion coefficient generally increases with temperature. This is because higher temperatures lead to greater thermal energy, which enhances the movement of particles, resulting in increased diffusion rates. The relationship between diffusion coefficient and temperature can often be described by Arrhenius equation or by simple proportional relationship in many cases.
What is temperature coefficient for insulator?
"Temperature coefficient" means, how does a certain physical quantity vary, depending on the temperature. In this case, the physical quantity in question is probably the electrical resistance, or the electrical resistivity.
What volume will it occupy at 45 c?
To determine the volume of a substance at a specific temperature, you would need to know the substance's initial volume, its coefficient of thermal expansion, and the change in temperature. Without this information, it is not possible to provide an accurate answer.
Does juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
Does coefficient of friction depend on temperature?
Yes, the coefficient of friction can be influenced by temperature. In general, the coefficient of friction tends to decrease with increasing temperature due to factors such as changes in surface interactions and material properties. However, this relationship can vary depending on the specific materials and conditions involved.
What happens when the temperature of a forward biased diode is increased?
What happens depends on the temperature coefficient of the diode. If that diode has a positive temperature coefficient, it resistance increases with increased temperature. A diode with a negative temperature coefficient does the opposite.
How diffusion coefficient depends on temperature?
The diffusion coefficient generally increases with temperature. This is because higher temperatures lead to greater thermal energy, which enhances the movement of particles, resulting in increased diffusion rates. The relationship between diffusion coefficient and temperature can often be described by Arrhenius equation or by simple proportional relationship in many cases.
What type tempcoefficient does the zener diode have?
negative tempareture It depends on the reverse voltage. Up to about 5.6 volts, the zener has a negative temperature coefficient. Beyond 5.6 volts it begins to show a positive temperature coefficient.
If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
What is the thermal expansion coefficient for steel c 15?
thermal expansion depends on Temperature and material of steel
What is the difference between positive and negative temperature coefficient of resistance?
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.
Fullform of ntc and ptc?
ntc: negative temperature coefficient ptc: positive temperature coefficient
How the coefficient of viscosity of a liquid changes with temperature?
The coefficient of viscosity of liquids decreases with an increases in temperature.
Does a safe reactor have a positive or negative 'temperature coefficient of reactivity'?
negative 'temperature coefficient of reactivity'
What is temperature cofficient in pn junction?
Temperature coefficient of the PN intersection voltage to balance the temperature coefficient of the warm voltage.
What is the relationship between resistance and temperature?
• ntc 'negative temperature coefficient': its resistance decreases as the temperature increases• ptc 'positive temperature coefficient': its resistance increases as the temperature increases
Do The resistance of a material generally increases as its temperature increases?
The answer to this depends on the material from which the resistance is made. For most materials resistance increases with increasing temperature. This is referred to as having a "positive temperature coefficient". Some materials have a negative temperature coefficient; these do have uses in electronics.
