Why does evaporation require that heat energy be added to a substance?
Heat is energy the substance needs to change it's state of matter (the more energy a substance has the higher it's temperature)
What do you call heat that is added or removed from a substance but does not change the state of the substance sensible heat latent heat super heat or radiation heat?
Latent Heat.
When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete
Do you need to increase or decrease the amount of heat energy to change a solid to a liquid?
Thermal (heat) energy must be added or removed in order to cause a change of state.
What is the conversion of one substance to another?
change in state
What state will most likely result if heat is added to a liquid?
It will change into a gas.Adding heat to or removing heat from a system may result in a temperature change and possibly a change of state. A liquid substance needs heat added to it in order to enter a gaseous state. If enough heat is added to a liquid substance it will change into a gas.
What do you change to cause a change in state?
Change the temperature or pressure or both, to change a substance from one state to another. (such as gas to liquid)
When heat is added to or removed from a substance it may change its state. What state will most likely result if heat is added to a liquid?
In that case, the liquid may eventually change to a gas.
What change in state requires an energy to be added to the substance?
All in the sequence : solid -> liquid -> gas -> plasma.
Adding or removing what makes substances change from one state to another?
A change of state is when a substance shifts from solid, liquid or gas to another state. This happens when heat is removed or added.
Why does evaporation require that heat energy be added to a substance?
Heat is energy the substance needs to change it's state of matter (the more energy a substance has the higher it's temperature)
When a substance from one state of matter to another it is called?
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
What causes a substance to change its state of matter?
As thermal energy increases or decreases, a substance will change state. This relates to temperature in that the higher the temperature of something, the greater its thermal energy.
What do you call heat that is added or removed from a substance but does not change the state of the substance sensible heat latent heat super heat or radiation heat?
Latent Heat.
Which change in state requires that energy be added to the substance?
A phase change from solid to liquid requires energy .likewise a liquid will vaporise into the gaseous state after appropriate increase in energy.
When a substance changes from one state of matter to another it is call?
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
What is required to cause something to melt?
Melting is a change of state of a substance caused by an increase in thermal energy, so heat is required to melt a substance.
