What is the continuous flow that occurs in a heated fluid because of differences of temperature and density?
convection current
When does expansion occur?
Expansion occurs when there is a change in volume due to increased temperature. Contraction occurs when there is a decrease in volume due to decreased temperature.
What state change happens during condensation?
The energy change that occurs during condensation is: temperature.
Air curents caused by temperature differences?
Yes, air currents are caused by temperature differences. The temperature differences occur vertically and horizontally and causes air currents and weather.
Convection occurs when a warm liquid or gas?
Convection occurs when a warm liquid or gas moves moves into a region where the surrounding liquid or gas is a different temperature. An example of this is a warm gas rising into a region where the surrounding gas is cooler due to the lower density of the warm gas. Movement of gases and liquid due to differences in density (because of differences in temperature) is referred to as "natural convection". When the movement is caused by another force such as a pump or a fan or a mixing blade, then it is termed "forced convection".
What happens when rust occurs?
temperature increases.
What happens to the temperature when a eclipses occurs?
you die
What is the continuous flow that occurs in a heated fluid because of differences of temperature and density?
convection current
What happens when adiabatic expansion of gas molecules occurs?
The temperature of the gas decrease.
What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
What happens after a nebula contract and its temperature increases 10 million k?
A supernova occurs.
What happens after a nebula contracts and it temperature increases to 10 million k?
A supernova occurs.
When does expansion occur?
Expansion occurs when there is a change in volume due to increased temperature. Contraction occurs when there is a decrease in volume due to decreased temperature.
What are the differences between respiration and transpiration?
Respiration happens 24/7 while transpiration only occurs when there is sunlight.
When an exothermic reaction occurs in a water solution what happens to the temperature of the solution?
The temperature rises. An "exothermic" reaction releases heat energy in the process.
What are the reasons that exfoliation of granite occurs?
Exfoliation of bodies of granite rock can occur from chemical weathering of the surface, differences in temperature, salt crystallization, and release of pressure.
What happens to relative humidity as the air temperature drops below dew point?
It stays at 100%.
