Is freezing chemical or physical property?
I would say that freezing point is a boiling property because there is no scientific evidence to suggest that it is or indeed ever will be a chemical property. Freezing point is a chemical reaction. Therefor this is a debatable question. Different people may have different views. This is mine."Freezing point" is usually termed as "melting point" in scientific circles. Melting point is defined as the temperature at which the solid and liquid phase of a substance coexist at equilibrium under the pressure of their own vapors. Ice and water coexist at equilibrium at temperature of 32 degrees F when only their own vapor pressures are acting upon them. However, the temperature difference at atmospheric pressure is negligible. As you can see, melting point (freezing point) only depends on the physical conditions acting on the substance, therefore, melting point (freezing point) is a physical property. Melting point is effected (lowered) by the addition of other molecules or ions to the substance. This effect is physical because it depends only upon the number of particles (molecules etc) added and no chemical reaction is required.
Is it a chemical or physical change when you freeze water?
Freezing water is a physical change because the molecules stay the same, only changing from a liquid to a solid state. Chemical changes involve the rearrangement of atoms or molecules to form new substances.
How do you write a formula with physical state?
Put a subscript ed letter or letters in parentheses next to the chemical substance. (s) is solid (H2O(s) is ice). (l) is liquid (H2O(l) is liquid water). (g) is gas (H2O(g) is water vapor). (aq) means something is dissolved in water (NaCl(aq)).
Is dissolution of s in cs2 is a chemical change?
dissolution is physical property
When water freezes it a physical change or chemical change?
Physical!Ice is H20(s) and Water is H2O(l)
What if your teacher floats a needle on the surface of a glass of water in a demonstration What property of water is being demonstrated?
The property being demonstrated is surface tension. Water has a high surface tension due to the cohesive forces between its molecules, causing the needle, which is less dense than water, to float on the surface instead of sinking.
Is boiling nitrogen in a laboratory a physical or chemical change?
Compression of nitrogen or any gas does not alter the chemical property...only changes involve in physical properties... On compression the gas molecules are come into more close..so it is pressurized..not change its chemical property...and whenever chances is come it s expand ..
When water vapor becomes s liquid?
it drips from somewhere
How does boiling affect water s state of matter matter?
Boiling causes water to change from its liquid state to a gaseous state, known as steam or water vapor. This transformation occurs when the water reaches its boiling point, typically 100°C (212°F) at sea level, where the molecules gain enough energy to break free from the liquid's surface. As a result, boiling is a physical change that alters the state of matter from liquid to gas.
What are the four phase symbols in chemistry?
The four phase symbols in chemistry are (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous (dissolved in water). These symbols are used to indicate the physical state of a substance in a chemical reaction or process.
Is graphite lubricant a chemical or physical property?
The lubricating property of graphite is a physical property. The graphite does not undergo a chemical change when used as a lubricant.
What can you say about an unknown compound with a disagreeable odor?
It reeks? Which is a physical property. It likely contains sulfur (S).
