What law states that mass cannot be created or destroyed in chemical or physical changes?
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
What is the major cause of changes in states of matter?
The major cause of changes in states of matter is the change in temperature.As the temperature decreases to certain limit, a gas will condenses into a liquid and a liquid will freeze into a solid. It also works the other way around. And so, when temperature increases to certain limit, a solid will melt into a liquid, and a liquid will evaporate into a gas. However, there are special cases where a solid can turn into a gas (skipping the liquid phase) through a process called sublimation.The temperatures at which these phase changes happen depend on the substances since different substances have different chemical make ups and bonding structures.
What changes from a solid to a gas but skips the liquid?
Carbon dioxide in it's solid form changes physical states from a solid directly to a gas (process called sublimation), and is more commonly known as dry ice.
What is the law that states that mass is neither created nor destroyed during chemical reactions or physical changes?
The law of conservation of matter states that matter cannot be created or destroyed in an ordinary chemical reaction.
What state of matter does not change in volume?
Changes in the states of matter - or phase changes - do entail changes in volume.
How are the state changes of similar to the states changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
Pressure changes have no effect on the entropy of substances in the blank or blank states?
liquids and solids
What is it called when the three states change?
changes of state are called phase changes.
How mass conserved during chemical and physical changes?
the of conservation of energy states that energy neither is created or destroyed it changes states the of conservation of mass states that mass neither is created or destroyed it only changes state
How are the states changes of water similar to the state changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
Breakdown of complex substances in living things?
The breakdown (usually in living systems) from complex substances to simpler substances is called catalysis. In terms of thermodynamics, the breakdown from more ordered (often more complex) states to more disordered (often simpler) states is called entropy.
What does light rays refracted by a concave lens do?
changes in a physical states of a substance is called physical changes.
When a substance changes states at different temperature and pressure this is called?
pasterisation
What are some things that have melting points?
All substances have a melting point.Water, for example, has a melting point. It is simply the temperature at which a substance changes states to a liquid.
What were the changes to the contition of the US called?
Changes to the Constitution are called amendments. Three-fourths of the states or 38 must ratify amendments for them to become part of the Constitution.
Affective states accompanied by physiological changes that often influence behavior are called?
motives
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
