What else can I help you with?
Does rock have to melt in order to change form?
No, rocks can change forms through processes like erosion, pressure, and heat without completely melting. Rocks can metamorphose through heat and pressure to form new types of rocks without fully melting.
What colour does bromine water change when you mix it with saturated fat?
Bromine water will change from orange to colourless when it is mixed with saturated fat.
What color does bromine water change when you mix it with unsaturated fat?
Bromine water changes from orange to colorless when mixed with unsaturated fats due to the addition reaction that occurs between bromine and the double bonds in the unsaturated fats.
Is bromine a solid liquid or gas when the arrangement of particles is close together in a regular pattern?
Any substance with an arrangement of particles close together in a regular pattern is a SOLID. It is, infact, probably the best definition of a crystalline solid we have. The interesting thing is that this bromine must have been cooled a lot because bromine is normally a liquid at room temperature and pressure.
Does ethene change from orange to colourless when it reacts with bromine water?
Yes, ethene reacts with bromine water to form a colourless solution. In the presence of ethene, the orange-brown color of bromine water disappears as bromine is consumed in the addition reaction with ethene to form a colourless compound.
What is the physical state of Br at room temperature?
The exact state of Bromine at Room temperature and pressure is between liquid and gas - as all liquids have a partial gas pressure. You can make its state change by degree by very minor changes in properties. But bromine's boiling is considered to be above room temperature.
Does melting point change from altitude to altitude?
Yes, the melting point of a substance can change with altitude due to the variation in atmospheric pressure. As altitude increases, atmospheric pressure decreases, which can affect the boiling and melting points of substances. Generally, lower pressure at higher altitudes can result in lower melting points for many substances.
Does melting point changes from altitude to altitude?
Yes, it does. It is do because with change in altitude their is change in temp. and pressure which also changes the melting point. The change in melting point could be small to large depending upon change in conditions at different altitudes.
What are the 5 differences of melting and boiling with reasons?
Temperature: Melting occurs at a specific temperature known as the melting point, while boiling occurs at the boiling point. Phase change: Melting involves solid turning into liquid, while boiling involves liquid turning into gas. Energy input: Melting requires energy to break intermolecular forces within the solid structure, while boiling requires energy to overcome intermolecular forces that hold the liquid together. End result: Melting results in a liquid, while boiling results in a gas. External pressure: Boiling point changes with external pressure, while melting point remains constant.
Two factors that are responsible for a phase change?
Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
What is the change of state in which a solid becomes a liquid by adding heat or changing pressure?
An electric car needs a little bit of gas to run
What mining of melting point?
The melting point is the temperature at the solid and liquid states of the material are in equilibrium; if the temperature is even very slightly above the melting point, the material will melt, and if it's even very slightly below, the material will freeze. Technically the melting point depends on the pressure, but usually the dependence is not very strong; you have to change the pressure a lot (and by "a lot" I mean many multiples of normal atmospheric pressure) to change the melting point by enough to even notice.
Does there occur any change in melting point of ice by variation of pressure?
Yes, increase in pressure causes the freezing point to drop.
What pr ocesses change sedimentary rocks into metamorphic rocks?
heat and pressure, but without melting.
In terms of rock cycle why do minerals and rocks change over time?
They change because of exposure to weathering, erosion, heat, pressure, and melting.
What is compressibility briefly?
Compressibility is the physical process of the volume change under the action of an external pressure.
Why is melting of butter is reversible whereas curdling of milk is irreversible?
Melting is a phase change, which is entirely controlled by temperature (pressure is also relevant but under normal circumstances, air pressure is approximately constant). Curdling is a chemical change. The process that leads to a particular chemical is much more complicated than a change in temperature.
