the glass and iron are not glowing... the glass and that metal ( an alloy of some sort) are all shiny so you cant tell the difference... why dont you heat a test tube with a jet flame about 5 seconds and then touch the glass quickly...you will notice my meaning.

when you heat things up the atoms begin to vibrate, therefore maybe when you touch hot things they become slippery due to the excited atoms. Or maybe it is your fingers how it looses its moisture and grip. I also touched hot metal quickly and it is slippery too.

Scientific work is indeed full of endless details, and also requires accuracy and determination without giving up. Science is certainly very interesting. Science is the key of life. Succeeding in science is one of the best feelings you can get! After all it is one of the hardest subject. You’re living because of the fact of science!

yes it is indeed the speed of light...the fastest speed known to man

when you touch hot glass why does it seem more slippery? What do you think?

should this talk about pyro continue? if so...the information will be pouring in. Is this legal?

Greetings. I am a student researcher. I am interested at every aspect of science and I dedicate my life towards science. As "YT2095" said:"i am a sciencehollic"...well im also another sciencehollic o,< I hope to learn from this site and possibly get to help others. "What is science?....Science is everything"

My textbook says that this equation for photosynthesis is more clear: 6CO2 + 12H2O -------> C6H12O6 + 6O2+6H2O is this true?

my friend did one in his mouth and it was safe. lol

An easy way to get H2SO4 H2SO4 can be purchased easily at a mechanic store. It will be calld as "Battery acid". as you realise it is very diluted, so all you have to do is to heat it and let all water to evaporate, that is when you see unpleasent gas start to appear. you shall do it out doors.

1.can anyone identify the difference between elements, compounds and mixtures in terms of particle theory. An element is a pure substance which cannot be decomposed into simpler substances. A compound is a pure substance which can be decomposed into simpler substances. For example, NaCl----->Na+Cl A mixture can be seperated into two or more pure substances by physical or mechanical means such as filtering, boiling or using a magnet or tweezers. -------------------------------------------------------------------------- 2. describe the phyiscal properties used to classify compounds as ionic or covalent molecular or covalent network. Ionic (a metal and a non-metal) 1) High melting and boiling points. 2) Conducts electricity only in molten or dissolved form. 3) Hard and brittle. 4) Electrostatic forces holds the particles together in the solid. Chemical examples: NaCl, CuSO4, (NH4)2SO4, Ca(OH)2, FeCl. -------------------------------------------------------------------------- Covalent 1) High melting and boiling points. 2) on electrical conductivity. 3) Hard and brittle 4) Covalent bonding throughout the crystal Chemical example: Sio, Diamond NOTE: Graphite is covalent but it conducts electricity. -------------------------------------------------------------------------- 3. describe using diagrams ionic compounds in terms of repeating three-dimensional lattices of ions. When sodium is burned in a chlorine atmosphere, it produces the compound sodium chloride. This has a high melting point (800 ºC) and dissolves in water to to give a conducting solution therefore sodium chloride is an ionic compound. Electrostatic attraction are in these oppositely charged ions packing together in a lattice. The attractive forces holding the ions in place can be referred to as ionic bonds. (i think thats what you're asking for) -------------------------------------------------------------------------- Hope i helped
