Wave Properties
Wave Properties - On observing waves, it may be observed that they travel with a definite speed through a uniform medium. If we watch a particular spot, we find that the waves pass that spot at regular intervals of time. The following definitions help in describing wave moti..
Properties of Matter
A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystalline. A solid is a crystalline subst..

Physical vs. chemical properties?This video demonstrates the difference between physical and chemical properties.
Question : Explain how physical and chemical properties of matter can be useful in correctly identifying a pure unknown substance.
Answer : physical properties give indication about a substance while chamical properties confirm it.
Answer : physical properties give indication about a substance while chamical properties confirm it.
Question : I wana to make an experiment using the gas sulphur hexafluoride, but i can't get the detail info. of the physical and chemical properties, so exsit there and lorded bloke can offer me a detail data, or help me calculate the question that how temperature and how much pressure i would give to the pure gas SF6 in a constant volumn of 120ml can make it up to 160bar.
thanks for your answer,
thanks very mcuh to the question that some bloke asked where I will make the experiment, well, my ex..
Answer : You just need is to the ideal gas equation... you just need is the number of moles of sulfur hexafluoride... So if you have one mole of SF6: PV=nRT (160 ba*1 atm/1.01325)(0.120 mL) = 1 mol (0.0821)T 18.94=0.0821T T=230 K or -42.45 C To know the chemical properties of SF6, look at these info: http://ptcl.chem.ox.ac.uk/MSDS/SU/sulfur_hexafluoride.html You must increase the temparature so that it can icrease the pressure but not decreasing the volume... I hope I'd answer your question
