IF WE KEEP A GLASS ROD IN HOT WATER WE CAN STILL HOLD THE GLASS ROD WITH OUR HAND.IT SHOWS THAT GLASS IS A GOOD CODUCTOR OF HEAT. WHETHER TRUE OR FALSE
false
If it were a good conductor of heat, then the glass rod would heat up all the way to the top and you might not be able to hold it.
False.
Glass is actually a poor conductor of heat. When a glass rod is placed in hot water, the heat is slowly conducted through the glass, but the process is relatively slow. Therefore, if a glass rod is left in hot water for an extended period of time, it would eventually become hot and unable to be held with bare hands. However, in a short span of time, the glass would not conduct heat quickly enough for it to become too hot to handle. This property of glass is why it is often used for insulating materials such as glassware and windows, as it does not readily transfer heat.
