What happens to water molecules as the temperature of water drops below 4 degrees Celsius but before it reaches 0 degrees Celsius?
As the temperature drops below 4 degrees Celsius, water molecules start to move slower and come closer together due to reduced thermal energy. This causes water to expand slightly, unlike most substances that contract when cooled. This unique behavior leads to water reaching its maximum density at 4 degrees Celsius.

What most likely happens to the rate of reaction of a human enzyme when the temperature is increased gradually from 10 degrees Celsius to 30 degrees Celsius?
The rate of reaction of a human enzyme typically increases as the temperature rises from 10 to 30 degrees Celsius due to increased kinetic energy, leading to more collisions between enzyme and substrate molecules. However, beyond the optimum temperature range, denaturation may occur, causing a decrease in enzyme activity.
What happens to oxygen over 100 degrees?
At temperatures over 100 degrees Celsius, oxygen remains in a gaseous state. However, if the temperature continues to rise significantly, oxygen molecules can break apart into individual oxygen atoms.
What happens when sulphur is at 115 degrees?
At 115 degrees Celsius, sulfur will change from a solid state to a liquid state. This temperature is above the melting point of sulfur, which is around 112.8 degrees Celsius.
What process happens at 0 degrees Celsius?
At 0 degrees Celsius, water freezes and turns into ice. This process involves the molecules in water slowing down and forming a solid crystal lattice structure.
What happens to amylase at 0 degrees Celsius?
At 0 degrees Celsius, amylase enzyme activity decreases significantly due to the cold temperature slowing down the kinetic energy of molecules, causing them to move more slowly and reducing the enzyme's effectiveness in catalyzing reactions. Amylase works optimally at higher temperatures closer to body temperature.
What happens to the movement of the molecules as the temperature rises from 0-100 degrees Celsius?
As the temperature rises from 0-100 degrees Celsius, the movement of the molecules increases. This is because the molecules gain more thermal energy, causing them to vibrate and move more rapidly. At 100 degrees Celsius, the molecules have enough energy to overcome the intermolecular forces holding them together, leading to the boiling of the substance.
What happens to the molecules of water vapor when the temperature of the gass cools to 100 degrees celecies?
Not sure what celecies means. If the temperature falls to 100 degrees Celsius, then at normal atmospheric pressure, the vapour molecules will condense into liquid water.
What happens to water at 4 degrees Celsius is heated slightly?
As water at 4 degrees Celsius is heated slightly, it will start to expand and the temperature will increase. This is because water is at its maximum density at 4 degrees Celsius, and heating it will cause the molecules to move faster and spread out, leading to a volume increase and a temperature rise.
What happens 0 C on the celsius temperature scale?
Water freezes at 0 degrees Celsius and at 32 degrees Fahrenheit.
What is the temperature of 100 Celsius in degrees?
100 degrees Celsius is the boiling point of water, which happens to be 212 degrees Fahrenheit at standard pressure
What happens to liquid water 0 degrees celsius?
At 0 degrees Celsius, liquid water freezes and turns into ice. This temperature is the freezing point of water, where the molecules slow down and form a solid lattice structure.
What happens to the molecules of water vapor when the temperature of gas cools to 100 degrees Celsius?
at standard pressure, the vapor condenses to liquid water at 100 C
What happens to the molecules of water vapor when the temperature of the gas cools 100 degrees Celsius?
at standard pressure, the vapor condenses to liquid water at 100 C
What happens to hydrogen at 20 degree's?
At 20 degrees Celsius, hydrogen remains a gas as it has a boiling point of around -253 degrees Celsius. At this temperature, hydrogen molecules continue to move independently and do not form any distinct structure.
What happens when the temperature of liquid water drops below 32 degrees Fahrenheit or 0 degrees Celsius?
When the temperature of liquid water drops below 32 degrees Fahrenheit or 0 degrees Celsius, it freezes and turns into solid ice. The water molecules slow down and form a rigid structure, causing the water to expand as it freezes.
What happens when water reaches 0 celsius?
When water reaches 0 degrees Celsius, it freezes and transforms into ice. At this temperature, the kinetic energy of the water molecules decreases, causing them to slow down and form a solid crystalline structure.
The room temperature increases from 20 degrees Celsius to 24 degrees Celsius what happens to the pressure inside a cylinder of oxygen contained in the room?
The pressure inside the cylinder of oxygen will increase as the temperature rises. This is because an increase in temperature causes the oxygen molecules to move faster and collide with the walls of the cylinder more frequently, resulting in a higher pressure.
