Why is cling film not a good insulator?
Cling film is not a good insulator because it is thin and flexible, which makes it easy for heat to transfer through it. Its low thermal resistance cannot effectively trap air and prevent heat loss or gain. Additionally, its material properties do not provide significant insulation against temperature changes.
Is sponge a good heat insulator?
Sponge is not a good heat insulator as it is porous and can easily transfer heat. Materials like cork or fiberglass are better heat insulators due to their low thermal conductivity.
Is zinc a good insulator?
No, zinc is not a good insulator. It is actually a good conductor of electricity and heat.
Is iron a insulator?
No because it is a good conductor of heat and electricity!
Is cling film a thermal conductor?
Cling film is considered to be a poor thermal conductor. It has low thermal conductivity, which means it does not readily transfer heat. This property makes it useful for wrapping food to keep it fresh as it does not easily conduct heat away from the food.

Sponge is not a good heat insulator as it is porous and can easily transfer heat. Materials like cork or fiberglass are better heat insulators due to their low thermal conductivity.
What is a good insulator and why?
a good insulator of heat keeps the heat in, so you stay warm
Why is insulation a good insulator?
a good insulator of heat keeps the heat in, so you stay warm
What does the term 'insulator' means?
insulator is a object that is not a good conductorSo it keeps the heat in.
Is nitrogen a good insulator of heat?
Nitrogen is not a good insulator of heat. It is a poor conductor of heat, but it is not an effective insulator as it does not trap heat well and can easily transfer heat through convection or conduction.
Is a sponge a good insulation?
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
What is the difference between a good insulator and a bad one?
A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
Is zinc a good insulator?
No, zinc is not a good insulator. It is actually a good conductor of electricity and heat.
Is iron a insulator?
No because it is a good conductor of heat and electricity!
Why is a wool a good insulator?
it is a good insulator because its a warm and keeps heat in by trapping it with air
Is aluminum a good heat insulator?
No. Aluminum is a very good conductor of heat.
