Sensible heat involves a change in a substance's?
Sensible heat refers to the heat that is exchanged by a body or thermodynamic system. It involves a change in a substance'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.
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
How much heat does it take to raise the temperature of a substance one degree?
The amount of heat required is called the specific sensible heat for the substance. Sensible, in this context, means something which can be sensed. This is in contrast to latent heat which is used to change the phase of a substance without a change in temperature.
What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
What are 2 reasons that a solution gets warmer when a new substance is added?
This is the effect of the heat of dissolution.
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.
How does specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
How does the specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
Is heat conductivity a physical change or chemical change?
The heat conductivity of a substance does not involve changes to its chemistry. Heat conductivity is a physical change and characteristic to a substance.
Sensible heat involves a change in a substance's?
Sensible heat refers to the heat that is exchanged by a body or thermodynamic system. It involves a change in a substance's temperature.
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
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.
Heat that causes a substance to change form is called?
latent heat :)
Heat which causes a change in temperature of substanceis called?
Heat which causes a change in temperature of substance is called specific heat.
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
Is toast browning a chemical or physical?
It is a chemical change. Look at the explanation below the picture of the rusting nail. With toast a new substance has been formed due to the heat which caused the chemical change.
