How does change of state take place?
for a state change to happen it must lose or gain or loose kinetic energy
What are the factors which determine a chemical change?
Factors that determine a chemical change include the types of substances involved, the presence of a catalyst, temperature, pressure, and concentration of reactants. Additionally, the activation energy required for the reaction to occur also plays a significant role in determining whether a chemical change will take place.
What change of state takes place when something sublimesfrom?
It is the phase change from a liquid to a gas.
Give three things you might see if a chemical reaction takes place?
There are many observations that may occur when a chemical reaction takes place. Some of the things are:- Change of colour, change of temperature change of state. These can be observed by the features below There might be a change in colour when mixing the reactants; the vessel in which the reaction is taking place might get warm on the outside or cold depending on the type of reaction. There may be effervescence or fizzing with gas production; a precipitate may form.
What observations does not indicate that a chemical change has occurred a. change of state b. formation of a precipitate c. absorption of energy d. release of a gas?
Change of state does not necessarily indicate a chemical change. It could be a physical change, such as melting or freezing, where the substance remains the same chemically. On the other hand, the formation of a precipitate, absorption of energy, and release of a gas are all indicators that a chemical change has occurred.
What are two observations you might make when a physical change occurs?
Change in state: One observation would be a change in the physical state of the substance, such as from solid to liquid or gas. Reversibility: Another observation might be that the physical change is typically reversible, meaning the substance can return to its original state by reversing the process that caused the change.
How does change of state take place?
for a state change to happen it must lose or gain or loose kinetic energy
How can one determine the entropy change in a system?
One can determine the entropy change in a system by calculating the difference between the entropy of the final state and the entropy of the initial state, taking into account any heat transfer and temperature changes.
What are the factors which determine a chemical change?
Factors that determine a chemical change include the types of substances involved, the presence of a catalyst, temperature, pressure, and concentration of reactants. Additionally, the activation energy required for the reaction to occur also plays a significant role in determining whether a chemical change will take place.

What type of change is a state of matter?
physical... the matter itself does not change. That would imply that a chemical change is taking place
What are the requirements for a liquor license at a guest house?
These regulations change from location-to-location and state-to-state. You must contact your state's liquor control agency to determine the requirements.
Determine how energy is related to change in state?
Energy is used to do work against in separating the mutually attracive atoms or molecules from each other to change them from solid into liquid and from liquid into gaseous state.
Does your employer have to notify you if they change the day you get paid on?
Not that I am aware of - although you may check with your state Department of Labor to determine if there are any state laws regarding this.
Why is a phase change a physical change and NOT a chemical change?
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
How do you determine the statute of limitations if you have moved?
That depends on many circumstances. Typically the laws of the place the event took place are key. But, leaving the state often tolls that limit.
