It is because the heat is driven out of your hand. That's the simplest I can put it.
No, smoke is not considered a transparent medium because it does not transmit rays of light through it. An example of a transparent medium would be glass.
Glass objects can be made through the lost-wax process
glass you can see through and fibreglass you can not
A magnifying glass is transparent, totally clear.
sand makes glass and glass make sand its a reverse psychology :)
It is because the heat is driven out of your hand. That's the simplest I can put it.
convection currents are used to transfer thermal energy through layers of glass
it can be transferred through metal...and glass...
Something that allow you to look through it Example : a glass a plastic bag a glass window Best example : the glass used in spectacles is transprent so people can see through it :)
via conduction. there are 3 types of heat transfer: conduction = transfer through direct touch convection = transfer through a liquid or gas radiation = transfer through electromagnetic waves
It is made of glass, heat can easily transfer through it, and it is also fragile.
If you are talking about electromagnetic waves then an easy example would be light travelling through glass. If you are talking about sound waves than you could use the example of sound travelling along a wooden floor.
For example, air, water, glass.
Yes, that is correct. (Slower than in a vacuum.)
radio/TV through the walls of your houselight through glass/plastic/jellomicrowave through meatloafX-ray through your teeth
because it can cut through the bag, cut the guy who is holding it and infect him with the chemical that is on the glass!
Enough light gets through so that you can see the image clearly.
