Place the back of your hand near the glassware in question and if you feel heat coming from it, do not touch it.
if a chemical splashes into your eye how long should you wash your eye (S). Why?
Put your hand close to it. If you still feel heat coming off of it, its probably still too hot to touch.
touch it . :)
Nothing because pouring hot water in glass will do nothing except fogging the glass as you pour the water
Hot glass is less likely to crack than cold glass. It's down to the temperature difference. If the glass is colder than the water, its outside heats up, and expands. Glass is a poor conductor of heat so the inside doesn't get hot and expand nearly as quickly. This sets up strains in the glass, and because it's brittle, it cracks. .Hot glass may still have a sufficiently different temperature from the water to cause the same effect
Rapid temperature changes can cause glass to crack. For the same reason you should never wash a hot glass with cold water.
Diamond should scratch a piece of glass.
The boiling point of oil is higher than water and absorbs more heat .When hot oil is poured in a glass container the heat is conducted through the cold glass which expands and breaks while in hot water the heat energy absorbed is less and the glass heat is dissipated slowly to avoid sudden expansion.
put the sugar and glass in a ffilter ant then hot water i think u tell me please im only eleven
Condensation of the cool air on the hot glass.
because the glass will pop if you put the very hot water into the glass
yes it has to be very hot for glass to break or melt
The hot liquid could crack a cold glass.

Liquid glass has more thermal energy because it's really hot. A normal glass bowl isn't as hot as liquid glass.
put the glass in the heater....................
Place the hot glass in a slight draught will help it to cool slowly and avoid cracking.

The hot water will increase the temperature of the glass and cause the inside of the gas to expand faster than the outside.This will exert a force on the glass and the glass may crack.
