1) melting-solid state changes into liquid state and
2)freezing-liquid state changes into solid state
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.
"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.
Not necessarily. Some chemical reactions may change the physical state of matter (e.g. solid to liquid), while others may not involve a change in physical state. It depends on the specific reaction and the properties of the substances involved.
state two examples for each of the four states of matter
Temperature and pressure are two factors.
Two ways in which physical state of matter can be changed:- changing the temperature- changing the pressure
Density and color can vary while the substance remains the same. Density is mass per unit volume, which can change depending on pressure or temperature. Color can vary due to factors such as lighting conditions or impurities in the substance.
Temperature and Pressure are the two main factors that determine the state of matter.
breaking or creating molecular bonds -- increasing or decreasing heat energy
by doing kantot ?? I am not sure about above answer, vulgarity aside but... State of matter refers to solid, liquid, gas, plasma and a couple of other new ones I am not sure of... Phase of matter refers to matter that has uniform properties throughout. They are sometimes used as synonymously. This often doesn't matter but be careful when discussing homogeneous versus heterogeneous chemical reactions. Phase means phase NOT state since two solids are not considered a homogeneous reaction (nor are two immiscible liquids) because they are not in the same phase when mixed (they do not have uniform properties when mixed) even though they are in the same state.
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
The 2 states of matter that are fluids are liquid and gas.
