What are two physical properties that can vary even when the substance with these properties dose not change?
The density and state of matter (solid, liquid, or gas) of a substance can change with changes in external conditions even in the absence of any change in the substance itself.
Does physical state of matter always change during a chemical change?
No. Two elements of the same state can combine and still be in the same state in the end product.
Explain how a change in thermal energy causes matter to change from one state to another. Give two examples?
It causes matter to change by turning water into gas which is vaporization. water into ice and burning wood into ash.
What are two examples for each of the state's of matter?
state two examples for each of the four states of matter
What are the two changes of state in matter?
"The" two changes are wrong. There are lots of different states of matter, and therefore many different possible transitions. The most commonly studied states of matter are solid, liquid, and gas; each of them can change directly to each of the others, for a total of 6 types of change.
Explain when a matter is in a state of equilibrium?
It is in equilibrium when the two conditions are satisfied - there is no net translational equilibrium and no net rotational equilibrium. For translational equilibrium, the summation of forces acting on the matter must equate to zero, which means that there is no resultant force. For rotational equilibrium, the sum of moments must be zero, which means there is no resultant torque. When these two conditions are met, the object will be stationary, i.e. it is in a state of equilibrium.
What are two ways in which the physical state of matter can be changed?
Two ways in which physical state of matter can be changed:- changing the temperature- changing the pressure
What determines a matter state of matter?
Temperature and pressure are two factors.
What are factors that determine the state of matter?
Temperature and Pressure are the two main factors that determine the state of matter.
What is two things that can cause matter to change from one state to another?
breaking or creating molecular bonds -- increasing or decreasing heat energy
What are the type of change of matter?
The two types of changes in matter that it goes through is physical change and chemical change... trust me, we are learning this at school.
What are two state of matter?
The 2 states of matter that are fluids are liquid and gas.
