Why does the temperature remains constant during the change of state?
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
What 2 things can make the pressure of gas rise?
1) Increase in heat 2)Decrease in volume
How and why do substances change volume when their temperature changes?
because of the set melting and freeZing points
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
How an increase in temperature change the rate constant of a chemical reaction?
yes ofcourse!
How does a substances temperature change when the average kinetic energy of it's particles increases?
As the average kinetic energy of a substance increases, the temperature will increase.
How does a substances temperature change when the average kinetic energy of its particles increases When it decreases?
It decreases in relation to lower temperature.
What causes substances to change phases?
The pressure and temperature mostly the temperature.
Why same amount of heat supplied to same amount of different substances does not produce the same increase in temperature?
There is a formula in physics ΔQ=m*c*ΔT, where m is the mass of the substance you are heating, ΔQ is the heat you supply to the substance, c is the specific heat which has a different value for different substances and ΔT is the change in temperature. If your substances are different and they have the same mass then by supplying the same amount of heat the change in temperature will be different.
What happens to substances temperature during a change of state?
Temperature remains constant
How does volume of matter change with increase in temperature?
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
Why do substances exist as gases?
At a given temperature practically all substances become a gas; it is a change of phase.
Does a child's temperature increase with growth?
no it do not change
What can cause a solid to change into a liquid?
A rise in temperature
What do chemical bonds have to do with a temperature change?
Substances with covalent bonds are more sensible to temperature changes.
Do mood rings work if they are 5 bucks?
Mood rings do not change on account of your mood, then change account of the temperature. When the temperature changes, the color of the ring changes.
What is DELTA T?
delta T or ▲T is the change of temperature. ▲T= (Final Temperature-Initial Temperature)
