Is making Sugar into sugar syrup a physical change or chemical change?
Unless you overdo it and carmelize it, it is a physical change. A typical process is to dissolve a large amount of sugar into hot water (physical change - the sugar is still sugar and the water is still water; they do not react. If the sugar-water is not syrupy enough, you can boil off some of the water (still a physical change). If you overdo it though, you will begin to caramelize the sugar. If the sugar is sucrose, it breaks down into fructose and sucrose along with a host of other side reactions that condense, isomerize, dehydrate, fragment, polymerize, and otherwise chemically change the original sugar. Caramelization is definitely a chemical change, but it is not necessary to make syrup.
Is a dead mouse a physical or chemical change?
When something is alive, there are chemical reactions going on constantly within it. The technical definition of being deadis that of chemical equilibrium. When a system (for example, a beaker with chemicals inside it, or an animal) is in chemical equilibrium, there is no reaction that can take place without an input of energy. Since an animal in chemical equilibrim cannot do anything, it is considered completely dead.So, in short, dying (that is, ceasing to be alive) is nota chemical change. Instead, dying is a lack of chemical change.
The dew comes up from the ground in the morning why in the morning?
dew doesnt come up from the ground it condenses from the air when the temperature drops which happens to be at its lowest just before sunrise
Do earthquakes usually begin deep in the ground?
yes
What are the chemical and physical properties of plastics?
Properties of PlasticSome physical properties: transparency, flexibility, elasticity, permeability, water resistant, electrical resistance, Specific Gravity, soft when hot.Some chemical properties: solubility, chemical resistance, thermal stability, reactivity with water, flammability, heat of combustion
Is scorching butter a physical or chemical change?
Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
What events happens in autumn?
In the autumn or fall, leaves begin to lose their chlorophyll and turn different colors. After that, the leaves lose their cohesion and fall to the ground.
What does a rock begin to do when it is exposed to weather?
It begins the process of weathering, involving physical and chemical attack.
What property chemical or physical would best describe the process of water evaporating from the oceans to begin the water cycle?
evaporation is a physical change
Why does 'take off' mean to begin to fly?
Take off is when the wheels of the aeroplane leaves the runway (ie the aeroplane takes off from the ground).
Scorching butter chemical or physical change?
Melting of butter is a physical change, a change of phase; but the brown color, at high temperature, is an indication of thermal decomposition - this ia a chemical change (change of composition).
When did composting begin?
Composting has been happening naturally in the wild nearly since the world began. When leaves fall off trees, they compost on the ground.
What is a physical change that takes place when oxygen and hydrogen are combined to form H2O?
When oxygen and hydrogen combine to form water there is a chemical change, not a physical change. That may be followed by a physical change, depending on the conditions when the chemical change occurs. You may, for example begin with water vapor and, if the temperature is low enough, it will condense (a physical change) to liquid water.
Are butter biscuits a chemical change?
It is not chemical change ,it is a physical change
Where does fall begin?
by leaves changing
Explain the chemical change that takes place in tree leaves?
Leaves change colors for the following reasons: Once the water supply is cut off in the fall, no more chemical reactions take place for the leaves to make their own food. As the chlorophyll dissipate from the leaves and there is no water, the leaves begin to dry up. Once the manufactoring of food stops completely, the leaves dry up and fall from the tree. The water is turned on by nature in the spring and the leaves begin to make more food and give off oxygen.
Is fragrance of a flower a chemical change?
Strictly speaking, the initial volatilizing (evaporation) of the perfume is a physical change but, soon after contact with oxygen, the volatile organic compounds and other components of the perfume begin oxidizing. In that case, there is a chemical change.
