When sugar canalize on being heated above its melting point is physical change or chemical?
When sugar caramelizes on being heated above its melting point, it undergoes a chemical change. This is because the heat causes the sugar molecules to break down and rearrange into new compounds, resulting in the formation of caramel.
What is the state of krypton at 20 degrees calcious?
At 20 degrees Celsius, krypton is a colorless and odorless gas. It remains in its gaseous state at this temperature. Krypton is a noble gas with a boiling point of -153.22 degrees Celsius, so at 20 degrees Celsius, it is well above its boiling point.
Is a raw egg cooked a physical or chemical change?
Chemical. If the component substances are the same at the end of the process, you have a physical change. If your object isn't made of the same substance at the end, it's chemical. Cooking denatures the proteins in the egg.------------------------------------------------------------------------------------------------------------------------No the above is incorrect.It is a physical change. The proteins forming the substance of the egg "denature" above about 60 degrees Celsius. Proteins are complexly folded molecules and the vibration caused by the application of heat causes them to unravel - Once untraveled they tangle up to form a solid and the processes irreversible but because the change is a change in shape it is physical not chemical.
What is the state of krypton at 20 degrees celsius?
At 20 degrees Celsius krypton is a gas. You would have to bring the temperature way down to just below -153.22 (yes, negative!) degrees Celsius for krypton to become a liquid, and just below -157.36 degrees Celsius to make it a solid!
Is panning a chemical change or physical change?
Panning is a physical change because it involves the movement of particles within a mixture, but no new substances are formed chemically. It is a separation technique based on differences in particle size and density.
Is density a physical change or chemical?
A change in density may accompany a Physical change. When liquid water becomes solid water, the solid water FLOATS; (is less dense) on top of its liquid form.Density itself is a physical property, not a change.
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.
Is ice melting a physical or chemical reaction?
Ice melting is a physical reaction, not a chemical one. It involves a phase change from solid to liquid as the temperature of ice increases above its melting point without any change in the chemical composition of the water molecules.
What is the layer that floats above the earth?
The earth's mantle.
Is play dough a chemical or physical change?
chemical
What is the physical state of krypton at -10 degrees celsius?
It is solid at this temperature at is likely frozen. Keep in mind that negative 150 degrees Celsius is equal to negative 238?ædegrees Fahrenheit.?æ
Why does ice float above and under water?
Ice floats above water, as it has lesser density than that of water. Due to anomalous expansion of water, the ice (solid) has more density than water(liquid). Hence, it floats above water.

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 sugar canalize on being heated above its melting point is physical change or chemical?
When sugar caramelizes on being heated above its melting point, it undergoes a chemical change. This is because the heat causes the sugar molecules to break down and rearrange into new compounds, resulting in the formation of caramel.
Is oil denser then water?
No. It is less dense. That's why it floats above water.
What is the green diamond that floats above a sims head called?
It is called a 'Plumbob'.
