What is the lowest recorded temperature on Jupiter?
The lowest temperature on Jupiter is 234.43 degrees
What is a PTC Relay?
Positive Temperature Coefficient).......by vamsi
Why should the coefficient of thermal expansion of a refractory metal be the lowest?
refractory metals have high melting points and are used in extremely hot environments; if expansion coefficient is lower this prevents high stresses that can develop due to thermal gradients during the high heat up. It helps to have high thermal conductivity as well
What classification of stars has the lowest surface temperature?
Black dwarfs have the lowest surface temperature.
What is the lowest temperature in Thimphu?
the lowest ever temperature in thimphu -36 degree celcious
What metal is the highest final temperature after the heat energy has been added?
The metal with the lowest thermal capacity.
What is the surface area of piezoelectric crystal?
All the (pairs of ) surfaces of a piezoelectric crystal do not have the same piezo properties. And the temperature coefficient also alters at different angles through the crystal. So commonly, the 'BT' cut is the one with the lowest temperature coefficient.
What metal has lowest thermal conductivity?
Mercury, apparently Bismuth has the lowest thermal condctivity of metals that are solid at room temperature.
Why a tightly fitting metal cap is opened by heating it slightly?
The metal cap has a high expansion coefficient when temperature rises. As it expands and the grip loosens.
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.
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.
Does a safe reactor have a positive or negative 'temperature coefficient of reactivity'?
negative 'temperature coefficient of reactivity'
How the coefficient of viscosity of a liquid changes with temperature?
The coefficient of viscosity of liquids decreases with an increases in temperature.
How diffusion coefficient depends on temperature?
The diffusion coefficient depends on temperature in direct negative exponent.
Fullform of ntc and ptc?
ntc: negative temperature coefficient ptc: positive temperature coefficient
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
