What is thermal runaway in a BJT?
Thermal runaway is where the biasing and operating point is such that the temperature causes the gain to increase, which causes the temperature to increase, which causes the gain to increase, in a vicious circle, leading to destruction of the BJT. Proper biasing and gain management can prevent this from occurring.
The addition of heat energy to a system always causes the temperature of that system to increase.?
Yes. Adding heat will increase temperature.
How does a temperature increase causes the rate of a reaction to increase?
It increases the kinetic energy of the molecules

When a volume of air is compressed its temperature does it increase or decrease or neither?
When a volume of air is compressed, its temperature increases due to an increase in kinetic energy of the air molecules. This is because the compression process causes the air molecules to be crowded closer together, leading to collisions that result in an increase in temperature.
What causes the greatest increase in the motion of molecules in a system?
Increasing the temperature of the system causes the greatest increase in the motion of molecules. This added energy results in faster molecular movement, leading to higher kinetic energy and increased collision frequency among molecules.
What does a warm front often produce that causes an increase in temperature?
A warm front can produce rain or precipitation that causes an increase in temperature. As the warm air replaces the colder air mass, it can lead to a rise in temperature due to the warm air circulating in the region.
When temperature increases density increases or decreases?
An increase in temperature usually causes an increase in volume. Since the mass doesn't change, density decreases. tt
Which gas causes an increase in the temperature in the stratosphere?
Ozone (O3) is a gas that causes an increase in temperature in the stratosphere. This is because ozone absorbs incoming ultraviolet (UV) radiation from the sun, which heats up the stratosphere.
What causes jalepenos to increase in heat?
High temperature and the perfect ripening time. :D
What can causes an increase in the density of the ocean water?
salt a decrease in temperature and an increasue in salinity
The ozone layer causes a temperature increase in the?
stratosphere. This temperature increase is due to the absorption of UV radiation by ozone molecules, leading to a warming effect in the upper atmosphere.
