When you mix two substances in a beaker and expect them to undergo a chemical change the temperature of the mixture does not change has a chemical change occurred?
a chemical change occurs
What occurs during temperature inversion?
A temperature inversion occurs when air temperature at the upper layer are much warmer than the lower layer of air..
What is the temperature that freezing occurs?
This is called the melting (or freezing) point
What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
Where does convection occur?
Convection occurs when and where a fluid is in a gravity field and heat is applied to its base.
What difference in temperature is needed for condensation?
It varies for the condensing vapor and humidity. Condensation occurs when a vapor is cooled to its dewpoint. See "dew point" for more information. It is not necessarily a difference in temperature, since it changes based on humidity and air temperature.
What is the use of water discharged from AC?
The water from an air conditioner you are referring to is known as condensation. This occurs when there is a difference in temperature between an object and the temperature of the air.
When does contaction occurs?
whenever it wants to, it can happen anytime and annywhere
When you mix two substances in a beaker and expect them to undergo a chemical change the temperature of the mixture does not change has a chemical change occurred?
a chemical change occurs
Why use LMTD and not mean temperature difference?
Because the temperature change that occurs across the heat exchanger from the entrance to the exit is not linear, and a logarithmic function best describes this temperature change.
During the afternoon the greatest temperature difference between the surface air and the air several meters above occurs on a?
clear calm afternoon
What to expect if an earthquake occurs?
expect the earth to shake little, things to fall, and get under atable.
Boiling only occurs at what particular temperature?
It occurs at 212 degrees.
Where retreating monsoon occurs rainfall?
The retreating rainfall monsoon occurs when the temperature on land is significantly warmer or cooler than the temperature of the ocean.
What are the 3 factors that affect how quickly diffusion occurs?
Relative molar mass, temperature, and concentration difference/gradient.
What happens when rust occurs?
temperature increases.
What happens to the temperature when a eclipses occurs?
you die
