Why is the glass shell on a flask a poor conductor?
The glass shell on a flask is a poor conductor of heat because glass is an insulator, meaning it does not easily transfer heat. This property helps to maintain the temperature of the contents inside the flask, whether hot or cold. Additionally, glass is a brittle material, so the shell acts as a protective barrier for the contents of the flask.
Is duct tape a good conductor of heat?
Duct tape is not a good conductor of heat. Its composition and thickness make it a poor conductor, so it does not readily transfer heat.
Is a pencil a good conductor of heat?
No, a pencil is not a good conductor of heat because it is made of graphite, which is a poor conductor of heat. Heat will not travel easily through a pencil, making it a good insulator rather than a conductor of heat.
How does a tight fitting plastic stopper on a flask minimise heat transfer?
It prevents heat transfer by convection as it prevents contact between the surrounding air and air inside the flask. It prevents heat transfer by conduction as it is a poor conductor of heat.
Is phosphate a good conductor of heat?
Phosphate is not a good conductor of heat. It is actually a poor conductor of heat due to its molecular structure, which hinders the transfer of heat energy. This property makes phosphate a good insulator rather than a conductor of heat.
Should you use a flask which is a good conductor of heat or poor conductor to keep the tea inside the flask warm?
You should use a flask that is a good insulator or poor conductor of heat to keep the tea warm. This will prevent heat from escaping the flask and help maintain the temperature of the tea for a longer period of time.
Must the base of a wok be a good conductor of heat?
Yes.

Is boron a good conductor of heat?
Yes it is but it is not good for electricity!!

Phosphate is not a good conductor of heat. It is actually a poor conductor of heat due to its molecular structure, which hinders the transfer of heat energy. This property makes phosphate a good insulator rather than a conductor of heat.
Is milk a good heat conductor?
No, milk is not a good conductor.
Why is aluminum the worst heat conductor?
Aluminium is a good conductor of heat.
What is a good heat conductor?
Copper and aluminum. Most heat sinks are made of Aluminum (cheap and a good conductor of heat).
Is calcium a good conductor of electricity and heat?
Yes, calcium is a good conductor of heat and electricity. Most metals are good conductors of heat and electricity. Most nonmetals are not good conductors of heat and electricity.
