What kind of change is condesation?
Condensation is a physical change in matter where a gas turns into a liquid when it loses heat energy. It occurs when the air cools down enough for water vapor to condense into droplets.
What kind of change requires energy to absorbed in order to take place?
Endothermic reactions require energy to be absorbed in order to take place. This means that the reactions absorb heat from their surroundings in order to proceed.
Can a physical change can change an object into a different kind of matter?
No, a physical change does not change an object into a different kind of matter. It only alters the form or appearance of the substance, such as size, shape, or state (solid, liquid, gas), without changing its chemical composition.
When your hand is on a heat pad what kind of heat transfer is happening?
When your hand is on a heat pad, heat transfer is occurring through conduction. This is because the heat from the pad is being directly transferred to your hand through physical contact.
What kind of change causes iron to rust is a physical change?
The process of iron rusting is a chemical change, not a physical change. It involves a chemical reaction between the iron, oxygen, and water in the environment, resulting in the formation of iron oxide (rust).
What kind of chemical reaction is hand sanitizer?
The evaporation of hand sanitizer is an endothermic reaction. This phase change, from liquid to vapor requires heat and the alcohol takes the heat from your hand to evaporate. Therefore you feel cooler. It is a physical change, not a chemical change.
Heat is eliminated during the process of freezing this loss of heat is considered what kind of change?
This loss of heat is considered a physical change.
When sandpaper smooths a piece of wood what kind of change is it?
this is a physical change
What kind of change is the change of matter?
It is a physical change.
What kind of change is a change of state?
A physical change.
What kind of change happens when a brick crumbles Physical or chemical?
It is a physical change.
What kind of change is melting and freezing?
physical change
Is an orange a physical or chemical change?
An orange is a physical object and is not any kind of "change"!
Is ice berg a physical or chemical change?
An 'iceberg' is no kind of change, but the melting and forming is a physical change.
What kind of change is needed to separate a mixture into its components?
A physical change is needed to separate a mixture into its components. This can be achieved through processes like filtration, distillation, chromatography, or evaporation, which rely on the differences in physical properties between the components of the mixture.
What kind of a change occurs when ice melts?
Physical change
What is type of change that doesnt involve the formation of a new kind of matter?
physical change
