Is a liquid at normal temperatures and pressures a physical or chemical change?
A liquid at normal temperatures and pressures is a physical change. When a substance changes from a solid to a liquid or from a gas to a liquid without any chemical reactions taking place, it is considered a physical change.
What do you do to change from a liquid to a gas at temperatures above those normal to liquid state?
boil
A change in state from a gas to a liquid?
If at "normal" temperatures, it is called condensation. If at extremely cold temperatures, it is called liquefaction.
What is the meaning of the word freezing?
It's the change of a liquid to a solid using low temperatures.
The change of state from a liquid to a gas that usually occurs at the surface of a liquid over a wide range of temperatures.?
This phenomenon is called evaporation.
What happens when liquid in a thermometer undergoes thermal expansion?
The liquid rises, indicating a temperature.
How does the solubility of sodium carbonate in water change with varying temperatures?
The solubility of sodium carbonate in water increases as the temperature rises. This means that more sodium carbonate can dissolve in water at higher temperatures compared to lower temperatures.
What is it called when temperature rises and liquid water vaporizes?
When temperature rises and liquid water vaporizes, the process is called "evaporation." This occurs when molecules in the liquid gain enough energy to overcome intermolecular forces and transition into the gaseous state. Evaporation is a critical part of the water cycle and can happen at any temperature, although it occurs more rapidly at higher temperatures.
What 2 things does antifreeze change?
because.... 333246 is the answer NOT!! :)
What can liquid thermometer measure?
A liquid thermometer can measure temperature by observing the expansion or contraction of a liquid, typically mercury or colored alcohol, within a calibrated glass tube. As the temperature rises, the liquid expands and rises in the tube, while it contracts and falls with decreasing temperature. Liquid thermometers are commonly used for measuring temperatures in various applications, including weather monitoring, cooking, and laboratory settings. They provide accurate readings within a specific temperature range, depending on the type of liquid used.
What is Changing from a frozen solid to a liquid?
When a substance changes from a frozen solid to a liquid, it undergoes the process of melting. This occurs when the temperature of the solid rises above its melting point, causing the solid structure to break down and transform into a liquid state.
Does the evaporation of liquid occurs at all temperature?
Yes, evaporation of liquid can occur at any temperature, but it increases as temperature rises. Evaporation is the process where molecules at the surface of a liquid gain enough energy to escape into the gas phase. This can happen at both room temperature and higher temperatures.
