What are the examples of endothermic changes?
Examples of endothermic changes include melting of ice, evaporation of water, and the reaction between citric acid and baking soda in a cold pack. These processes absorb energy from their surroundings, causing a decrease in temperature.
Two examples of physical changes?
putting water in to the refrigerator to freeze it cutting wood dropping plates, or cups chopping fruits or vegetables tearing paper breaking items chewing pencils peeling potatoes
What are 2 examples of a physical change?
Melting ice into water and breaking a glass bottle are examples of physical changes. These changes do not alter the chemical composition of the substances involved, only their physical state or appearance.
Describe a network solid and give two examples?
Network solids are hard and brittle. They have high melting points. They DO NOT conduct electricity, unless they are liquified. They form crystals with geometric shapes that cleave along planes. Two examples are Diamond, or repeating blocs of C, and Sand, or SiO2.
During melting, what two states of matter are present?
During melting, both the solid and liquid states of matter are present.
What are two important properties of elements?
Examples: density, melting point, refractive index.

What are the two physical properties of zinc iodide?
Examples:- density: 4,74 g/cm3- melting point: 446 oC- crystal structure: tetragonal
What are two ways to separate a solution that contains two liquids?
you can separate a solution by evaporating it, melting it and by heating it
What are four examples of physical change?
Melting, Crushing, Mixing and Burning :)
What is formula of cupric sulphate?
Examples: melting point, boiling point, density.
What actions brings about physical change?
Examples: sublimation, melting, evaporation etc.
What are some physical changes of nickel?
Examples: melting, boiling, mechanical processing.
Melting is an example of a?
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
What is examples of heterogenous mixture?
Any mixture with substances with two or more phases are known as heterogeneous mixtures. Among the common examples are a system of a saturated solution of sodium bicarbonate in contact with solid and melting ice in contact with liquid water.
