How do you use the term physical change in a sentence?
A rubber band undergoes a physical change when it is stretched and pulled.
Can gold turn into steam?
Yes, gold can turn into steam if it is heated to its boiling point of 2,856 degrees Celsius (5,173 degrees Fahrenheit). At temperatures above this point, the solid gold will transition directly into a gaseous state without going through a liquid phase.
How can water be evaporated without boiling?
Water can be evaporated without boiling through a process called evaporation, where water molecules at the surface gain enough energy to escape into the air as vapor. This can happen at any temperature, not just boiling point.
How does water evaporate without boiling?
Water can evaporate without boiling when it reaches a certain temperature called the "boiling point." This happens when the water molecules gain enough energy to break free from the liquid and turn into vapor. Evaporation can occur at any temperature, not just the boiling point, as long as there is enough heat energy present to allow the water molecules to escape into the air.
Can kinetic energy of a system be changed without changing its momentum?
Yes, the kinetic energy of a system can be changed without changing its momentum if there is an external force acting on the system. For example, if friction is present, kinetic energy can be converted to other forms (such as heat) without affecting momentum.
How a liquid can be changed to gaseous from below its boliling point without supplying it with heat energy?
A liquid can be changed to a gas below its boiling point by reducing the pressure above the liquid. This process, known as evaporation or vaporization, allows the liquid molecules to escape into the gas phase without adding heat energy. This is how clothes dry outside even on a cool day.
What is the defintion of evaporation?
a process in which something is changed from a liquid to a vapour without its temperature reaching boiling point
How does the boiling point of a hydrocarbon change in presence of hydrogen?
It can NOT be changed by the presence of hydrogen without chemical reaction.
Is water boils at 212 degrees F chemical or physical?
The boiling of water at 212 degrees Fahrenheit is a physical change. This change occurs when water transitions from a liquid state to a gaseous state without altering its chemical composition.
Suggest how can liquid be changed into a gas without supplying heat energy?
it depends since water can change back to its hydrogen and oxygen gas forms when electric currents are applied.
How do you use the term physical change in a sentence?
A rubber band undergoes a physical change when it is stretched and pulled.
Can the molecular structure of potatoes be changed?
No, the molecular structure of potatoes cannot be changed without extensive genetic modification or biochemical processes. However, the physical and chemical properties of potatoes can be altered through cooking methods such as boiling, frying, or baking.
What do you call changes liquid to gas?
The process of changing a liquid to a gas is called evaporation. This happens when the liquid absorbs enough heat energy to break its intermolecular bonds and transform into a gaseous state, without reaching its boiling point.
Can gold turn into steam?
Yes, gold can turn into steam if it is heated to its boiling point of 2,856 degrees Celsius (5,173 degrees Fahrenheit). At temperatures above this point, the solid gold will transition directly into a gaseous state without going through a liquid phase.
How liquid can change in gas without supplying heat?
it isn't possible.With no heat and water, you have no gas.
How can I cook lasagna noodles without boiling them?
You can cook lasagna noodles without boiling them by soaking them in hot water for about 30 minutes until they become soft.
To change from a liquid to a gas without boiling?
To evaporate.
