through metabolism
How does an increase in temperature account for the fact that substances change state?
An increase in temperature changes the state because it melts it
What happens to a stars nuclear energy generation change if the core decreases in temperature?
What happens to a stars nuclear energy generation change if the core decreases in temperature?
How and why do substances change volume when their temperature changes?
because of the set melting and freeZing points
What happens to substances temperature during a change of state?
Temperature remains constant
What happens When a substance goes through a physical change?
The Substances die
What happens to mass when substances go through a chemical change?
The total mass of products is unchanged from the total mass of the reactants, but the masses of particular substances among the reactants or products change.
What causes substances to change phases?
The pressure and temperature mostly the temperature.
Reactants?
The Substances before he change happens.
What happens to temperature during a phase change?
Temperature is constant during a phase change.
Why do substances exist as gases?
At a given temperature practically all substances become a gas; it is a change of phase.
What happens to substances in a chemical change?
It creates a new mixture and is irreversible.
What do chemical bonds have to do with a temperature change?
Substances with covalent bonds are more sensible to temperature changes.
How do enzymes change other substances into?
through metabolism
Why does a chemical change in temperature indicate that a chemical reaction may have occurred?
A change of temperature implies that some energy has been transfered or used. Since chemical reactions either require or release energy to occur, the environment may change temperature as the substances react.
Does a substance change density if it changes physically?
Depends on what you consider a physical change. Substances change their density when they change their state of matter. When the temperature rises, substances usually expand, wich leads to the density decreasing. When the temperature falls, substances contract, increasing the density. Exception would be water, as it shows an anomaly occurring near 273K
