The water vapor then condenses and becomes a liquid again.
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.
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.
Was that on purpose? Because it just so happens that -40 is where the two meet! -40 degrees Celsius = -40 degrees Fahrenheit. Was that on purpose? Because it just so happens that -40 is where the two meet! -40 degrees Celsius = -40 degrees Fahrenheit.
At 20 degrees Celsius, uranium is a solid metal with a silvery-gray appearance. It has a density similar to that of lead and is a relatively stable element at this temperature. Uranium does not undergo any significant changes in its physical or chemical properties at 20 degrees Celsius.
solid
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.
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.
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.
Water freezes at 0 degrees Celsius and at 32 degrees Fahrenheit.
100 degrees Celsius is the boiling point of water, which happens to be 212 degrees Fahrenheit at standard pressure
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.
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.

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.
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.
