What else can I help you with?
Is sweat evaporating from your forehead a chemical change?
No, sweat evaporating from your forehead is a physical change, not a chemical change. The sweat is merely changing from a liquid state to a gas state without any change in its chemical composition.
What change of state does sweat go through?
Sweat undergoes the change of state from a liquid to a gas when it evaporates off the skin. This process helps cool down the body by releasing heat as the sweat vaporizes into the air.
What change of state does involve?
liquid to gas
Why is sweat evaporating a physical change?
Sweat evaporating is considered a physical change because it is a change in the state of matter from liquid (sweat) to gas (water vapor) without altering the chemical composition of the substances involved. The molecules in sweat retain their chemical identity during the process of evaporation.
When your sweat evaporates is that a chemical change?
No, the evaporation of sweat is a physical change, not a chemical change. Evaporation simply involves a change in state from liquid to gas, without any change in the chemical composition of the substance.
What change in state is involved in sweating?
it involves a lot of states i think it involves liguid to gas cause you sweat is liquid tehn the odur is gas
What does physical change does not involve?
A physical change does not involve a change in the chemical composition or nature of the substance. It only affects the physical properties, such as shape, size, or state of matter.
Enthalpy changes accompanying a change of state are than those accompanying the heating of a substance at each state?
The enthalpy changes accompanying a change of state (e.g., melting, boiling) involve breaking or forming intermolecular forces, which may require more energy than simply raising the temperature of a substance at that state. This is because changes of state involve a phase transition, which requires additional energy to overcome the intermolecular forces holding the substance together.
Does not involve the movement of matter?
A physical change involves a change in appearance, shape, or form of a substance but does not involve a change in its chemical composition. Examples include changes in state (solid, liquid, gas), size, or shape.
What are the two types of changes that chemists are primarily interested in?
Chemists are primarily interested in studying physical changes, which involve a change in appearance or state of matter without a change in composition, and chemical changes, which involve a change in the chemical composition of a substance.
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
Is sweat a chemical or physical change?
