Difference between eutectic and pereutectic points?
> A eutectic transformation, in which a two component single phase liquid is cooled and transforms into two solid phases.> A peritectic transformation, in which a two component single phase solid is heated and transforms into a solid phase and a liquid phase.
Describe 2 physical changes?
The two types of physical properties are intensive and extensive. Intensive properties do not depend on the amount of a substance. An example of an intensive property is density. Extensive properties do depend on the amount of a substance. An example of an extensive property is mass.
State two physical properties of wood?
Two obvious physical properties of wood are the following: it is a solid, it shrinks and expands with the loss and gain of water.
What is the phase in chemistry where a gas chnges to a solid?
Solid to Gas phase change is called Sublimation
Element with both metallic and nonmetallic properties?
The items that contain more than one element and have metallic properties are known as alloys. They can be an intermetallic compound that lacks phase boundaries, a metallic phase mixture, or a solid element solution.
Two basic properties of the liquid phase are?
it has no definite shape no definite volume
What are two basic properties of matter?
The two basic properties are:1) Something which has,Inertia,Volume,Mass.2) It has no definite State among 4 which are-- Solid-Liquid-Gas-Plasma.

What are two physical properties of silver (Ag)?
grey solid
What phase of matter has a definite size and shape?
Answer. A solid, the other two states are amorphous
Is wood a sublimatory substance?
No. A sublimatory substance changes from the solid phase directly to the gas phase without passing through a liquid phase. Two examples are dry ice (solid CO2) and iodine.
What is an example of a phase?
water vapor
What are two other wave properties besides amplitude and frequency?
Waves have other properties like Phase and Longitudinal or Transverse mode..
