If you remove large amounts of heat from a liquid what could happen?
Remove enough heat from the liquid, it changes to a solid- known as freezing.
Does freezing lose heat or add heat?
Endothermic reactions absorb heat, while exothermic reactions emit heat. Both can be used to generate freezing depending on various chemical compounds.
What happens to molecules from which heat is removed?
The molecules move slower when heat is removed.
If 2500 cal. of heat is supplied to 10g of iron at 10c what is the final temperature of iron?
If 2500 cal. of heat were supplied to 10g of iron at 10c what is the final temperature of iron?
What happens during a change in state?
Changes in the state of matter occur when the amount of heat energy is changed in a substance. When it is removed, gas condenses and liquid freezes. When it is added, solids melt and liquids boil.
Explain melting and freezing according to the kintic theory of matter?
When heat is supplied to a solid, the kinetic energy of the particles increases, they move away from each other
If you remove large amounts of heat from a liquid what could happen?
Remove enough heat from the liquid, it changes to a solid- known as freezing.
How are the processes of heating and freezing related?
They both have to do with the transfer of heat. Heating an object is transferring heat into the system. Freezing an object is transferring heat out of the system.
What will happen when heat is supplied to ice?
it melts
What can be removed from an atom if ionization energy is supplied?
an electron, bro
What happens to the heat energy which is supplied to the solid once it starts melting?
when solid has already melted and when heat is supplied it starts increasing the temperature of liquid
When freezing happens is energy added?
No, energy is removed.
What type of heat is removed when humidity is removed from the air?
Latent Heat
Does freezing lose heat or add heat?
Endothermic reactions absorb heat, while exothermic reactions emit heat. Both can be used to generate freezing depending on various chemical compounds.
What happens when a liquid reaches its freezing point?
A liquid at the freezing point might remain a liquid indefinitely if no more heat is removed. A liquid in frozen state might remain frozen indefinitely, too. If the liquid is very pure, it might remain a liquid even when carefully brought below the freezing point. It would shift phases if some impurity or movement disturbs the liquid. If enough additional heat (heat of fusion) is removed from a liquid at the freezing point then the liquid will freeze without changing temperature. If a frozen liquid has the heat of fusion added to it, it will melt without changing temperature.
When heat is supplied to a solid substance what happens to the energy?
The energy must be supplied to the solid so that it melts.
Is Freezing a Thermal Energy Added?
No, freezing is a result of losing thermal energy (heat).
