What occurs at the freezing point of a substance?
At the freezing point a substance become a solid.
Molecules are not in random motion when that substance is at?
Molecules are not in random motion when a substance is at absolute zero, the lowest possible temperature at which molecular motion ceases. At this point, molecular movement only exists due to the zero-point energy, preventing complete immobilization.
What substance is used to raise the water freezing point?
A substance commonly used to raise the freezing point of water is salt. When dissolved in water, salt disrupts the water molecules' ability to form solid ice crystals at 0°C, resulting in a lower freezing point.
Is the melting point the same temperature as the freezing point for a substance?

Are molecules moving?
Yes, molecules are in constant motion. This motion is known as Brownian motion, where molecules move randomly due to their kinetic energy. This movement is essential for processes such as diffusion and chemical reactions.
What is the purpose of a freezing point apparatus in determining the freezing point of a substance?
The purpose of a freezing point apparatus is to accurately measure the temperature at which a substance changes from a liquid to a solid state, known as its freezing point. This information is important for identifying and characterizing the substance.
What is its melting point when the freezing point of a substance is 68C?
The freezing point is 680C
Are the melting point of solid and freezing point of liquid of a substance different?
yes the melting point of solid and freezing point of liquid of a substance is differ but in the case of water the melting and freezing point is same.
The freezing point of a substance is?
The freezing point of water in Celsius is 0 degrees Celsius. The freezing point in Fahrenheit is 32 degrees Fahrenheit.
If the freezing point of a particular substance is 52 degrees celsius then what would its melting point be?
The freezing point and melting point of a substance are the same, so the melting point would also be 52 degrees celsius.
How is the freezing point of a substance related to the melting point of the substance?
The freezing point and melting point of a substance are the same temperature but represent opposite phase transitions. The freezing point is the temperature at which a liquid turns into a solid, while the melting point is the temperature at which a solid turns into a liquid.
What is the trend for freezing point?
As pressure increases, the freezing point of a substance generally decreases. Conversely, as pressure decreases, the freezing point of a substance generally increases. This relationship is described by the phase diagram of that substance.
