What will happen to the kinetic energy of gas molecules trapped in a rigid container if the temperature is increased?
increased
Five factors that affect resistance?
Electrical Resistance depends on three factors: Resistivity; Area; Length.Resistivity is the property of the matter. More Resistivity means more resistance.More Area means less resistance.More length means more resistance.R= Resistivity. Length/Area
Is resistivity of a conductor temperature dependent?
A perfect insulator has infinite ohms of resistance.
What combination of factors is most suitable for increasing the electrical conductivity of metals?
Resistivity is a constant for any particular material, and independent of that material's physical dimensions or shape. However, it does vary with temperature which is why resistivity is always quoted at a particular temperature. Variations in resistivity due to temperature change is the reason that the resistance of a material varies with temperature. In SI, resistivity is expressed in ohm metres.
Why does planetary cooling happen?
Because of the second law of thermodynamics , law of entropy. "when energy flows from a high-temperature object to a low-temperature object, the source temperature is decreased while the sink temperature is increased; hence temperature differences tend to diminish over time."
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
When the length is increased 2 times the value for resistivity will be?
The value for resistivity will remain unchanged (provided temperature remains constant). Resistivity is a property of the material. The resistance, however, will double. Remember that resistance is directly proportianal to the length of the conductor and inversely proportional to the cross-sectional area of the conductor.
What is the difference between metal and semiconductor?
A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.
What happen to the speed if the particles if the temperature is increased?
It increases.
The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
What will happen to the pH if the temperature is increased?
Nothing if nothing evaporates.
What will happen to the kinetic energy of gas molecules trapped in a rigid container if the temperature is increased?
increased
What happen to the range of energies of the particles in matter when the temperature is increased?
the range of energies becomes broader, or increases, as the temperature is increased.
What happen to the rate of dissolution as the temperature is increased in a gas solution?
The rate decreases.
What will happen to the amount of infrared radiation emit if an objects temperature is increased?
Increase
What must happen for a superconductor to work?
Super conductor will have zero resistance or zero resistivity. This happens when the temperature of the conductor reaches a very low temperature known as critical super conducting transition temperature. In case of mercury it will be 4.2K.
