What property do the following elements have in common sulfur iodine and magnesium?
Sulfur, iodine, and magnesium are all chemical elements found on the periodic table. They each have unique physical and chemical properties, but all three are solid at room temperature.
Is temperature a chemical change?
No, temperature is not a chemical change. Temperature is a measure of the average kinetic energy of particles in a substance and does not involve the rearrangement of atoms or formation of new substances.
What is the chemical equation of evaporation?
The process of evaporation does not have a specific chemical equation since it is a physical process rather than a chemical reaction. Evaporation involves the conversion of a liquid into a gas due to an increase in temperature, leading to the escape of individual molecules from the surface of the liquid.
What happens when a flask is heated up with a burner after ten minutes?
If a flask is heated up with a burner for ten minutes, the temperature of the liquid inside the flask will increase. This increase in temperature can lead to changes in the properties of the liquid, such as expansion, evaporation, or chemical reactions, depending on the type of liquid and the temperature reached. It is important to monitor the temperature carefully to prevent overheating or boiling over.
How are evaporation and transformation different?
Evaporation is a phase change process in which a liquid turns into a gas at the surface of the liquid, while transformation refers to a change in the structure or composition of a substance, such as in chemical reactions or physical changes. Evaporation typically involves only a change in state, while transformation can involve various changes beyond state, such as chemical composition or physical properties.
Is evaporation a chemical reaction?
No, evaporation is a physical process in which a liquid substance changes into a gas state at a temperature below its boiling point. Unlike chemical reactions, evaporation does not involve any change in the chemical composition or structure of the substance.
Can temperature change chemical properties?
yes it can!!
Can you think why are evaporation and boiling reversible changes?
They are reversible changes because they don't lead to the changes in chemical properties like boiling point, melting point, no. of electrons, etc. but changes the physical properties like mass, temperature, pressure, etc.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Does a chemical reaction change physical properties or chemical?
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
How do the physical and chemical properties properties of the elements change?
periodically within a group
What is the balance of chemical equation involve in evaporation?
Evaporation is not a chemical change and so there is no chemical equation.
How a temperature change is not a chemical change?
Change in temperature is not a chemical change rather it is a physical change because it does not cause any change in composition or chemical properties of matter.
Which in the following events is not a common sign that a chemical change taken place?
For example melting, boiling, evaporation, transformation in powder are not signs of a chemical reaction.
What property do the following elements have in common sulfur iodine and magnesium?
Sulfur, iodine, and magnesium are all chemical elements found on the periodic table. They each have unique physical and chemical properties, but all three are solid at room temperature.
Is temperature a chemical change?
No, temperature is not a chemical change. Temperature is a measure of the average kinetic energy of particles in a substance and does not involve the rearrangement of atoms or formation of new substances.
What generally occurs as temperature increases?
As temperature increases, molecular motion within substances generally accelerates, leading to changes in states of matter, such as solid to liquid (melting) or liquid to gas (evaporation). This increase in kinetic energy can also enhance chemical reaction rates, as reactant molecules collide more frequently and with greater energy. Additionally, higher temperatures can result in increased evaporation rates in liquids and altered behaviors in gases, such as expansion. Overall, temperature plays a crucial role in determining the physical and chemical properties of materials.
