What else can I help you with?
What two changes of state take place during distillation?
The two changes of state involved in freeze drying are melting and freezing.
What will happen if you put water in a dark cold place?
If you put a fish in a dark place the colour of the fish would gradually turn white.
What temperature does melting occur?
Melting occurs when a substance absorbs heat energy. The rigid crystal structure of the particles breaks down, and the particles are free to flow around one another.
What is the temperature that a solid begins to turn into a liquid?
The temperature at which a solid turns into a liquid is known as the melting point. It is the point at which the solid's internal energy overcomes its intermolecular forces holding its particles in place.
Why do particles in a solid eventually break away from their fixed positions when the solid is heated?
They begin to move around from place to place. We say the solid melts.
What two changes of state take place during distillation?
The two changes of state involved in freeze drying are melting and freezing.
What do you need to stop ice from melting?
To stop ice from melting, you can reduce its exposure to heat by keeping it in a well-insulated container or adding more ice to maintain its cold temperature. You could also use ice packs or place the ice in a cooler with insulating material to slow down the melting process.
What temperature do its particles become fixed into place as water it cooled?
The temperature at which water particles become fixed into place as it cools is 0 degrees Celsius, when it freezes and turns into ice.
How can I prevent my ice cream from melting quickly in the summer heat by using freezing ice?
To prevent ice cream from melting quickly in the summer heat, place the ice cream container in a larger container filled with ice. The cold temperature from the ice will help keep the ice cream cold and prevent it from melting too quickly.
What substance can be converted from liquid to solid and can not be converted back to liquid?
There is no such substance. Because only a transformation of physical state is taking place. Let me expand: Every substance has a specific temperature at which it changes its physical state. The temp. at which the substance turns into liquid is known as melting point and the temp. at which the liquid turns to solid is known as freezing point. Usually the melting point and the freezing points of a substance are the same. (But there are certain exeptions to this rule.) So if the temperature at which the substance turns into liquid is acheived i.e the melting point - then it definitely would become liquid again.
How do particles of a substance behave at its melting point?
At a substance's melting point, its particles transition from a fixed, ordered arrangement to a more disordered state as they gain enough thermal energy to overcome the intermolecular forces holding them in place. During this process, the temperature remains constant as the energy is used to break these intermolecular forces rather than increase the temperature.
Differentiate between freezing and refrigeration?
Freezing is a transition phase in which liquid turn to solid when its temperature is below its freezing point While Refrigeration is the removal of heat from a substance or a place and the heat is transferred to another substance or place .
How do you do freezing point of water?
Place the water in an area that has a temperature of under 0 degrees Celsius. A freezer will do.
When do snowstorms take place?
When there is a large concentration of water in cloud formation, when the air temperature is below freezing.
What will happen if you put water in a dark cold place?
If you put a fish in a dark place the colour of the fish would gradually turn white.
Is ice cream melting in a bowl a chemical change?
No. It is purely a physical change, that of melting. No chemical reaction takes place.
As water is cooled at what temperature do its particles become fixed in place?
Water particles become fixed in place and form a solid structure at 0 degrees Celsius, which is when water freezes and turns into ice.
