Endothermic reactions absorb heat, while exothermic reactions emit heat. Both can be used to generate freezing depending on various chemical compounds.

Would you add heat or take away heat to freeze a liquid?
Freezing is an exothermic process.
Is heat supplied or removed in freezing?
heat is removed in freezing .
When gases lose heat they into liquids?
When gasses lose heat they condense into liquids.
What is meant by the heat of fusion or substance?
That's the amount of heat you have to add to the solid form at the melting temperature in order to melt it to the liquid form at the same temperature. Looking at it the other way: It's the amount of heat you have to remove from the liquid at the freezing temperature in order to freeze it solid at the same temperature.
Why is the meting and freezing point of a substance the same?
Melting is simply the reverse of freezing. The secret to it is that it takes quite a bit of heat movement to make a substance change from the freezing point. Heat moves out of substance in freezing, and heat moves into a substance to make it thaw.
How do you stop water from freezing?
heat it up, add energy to it
Would you add heat or take away heat to freeze a liquid?
Freezing is an exothermic process.
Does heat affect the freezing water?
Yes - it takes longer to freeze water if you add heat - or melts it, if already frozen
The function of the condenser is too increase refrigeration pressure lose the heat from the refrigerant add heat to the refrigerant reduce the fridge aration pressure?
lose the heat from the refrigerant
Is heat supplied or removed in freezing?
heat is removed in freezing .
What happens when you add salt to ice why?
The freezing point of water decrease because the dissolution is a process which release heat.
How do you winterize a summer home?
Add heat, insulation, good windows, and (if needed) re-run the pipes to reduce the chance of freezing.
Does wind chill factors below freezing affect birds?
It does affect birds by the speed of the making it lose its body heat but not enough to hurt the birds.
What is the difference between freezing and melting?
Melting is when you heat something up and it turns from a solid state into a liquid state, such as adding heat to ice (solid) melts it to water (liquid). Freezing is the opposite, so cooling a liquid until it becomes a solid.
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.
Does freezing lose thermal energy?
yes
If a person is planning to take a mixture of milk and sugar and make it into ice cream do you expect the person to add or remove heat energy?
You would expect a person to remove heat energy via freezing.
