yes
no i think i am right ( i hope )
yes
Air has a higher specific heat capacity (at 1.0035 J/(g*K)) than concrete (.880 J/(g*K)).Specific heat capacity is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by unit degree (Wikipedia). Because air requires more joules of energy per gram to raise it one degree Kelvin than concrete does, it is therefore a better insulator.
Ryan longstaf sed yes
Glass has a higher conductivity than thin plastic but,it is still lower than metal so metal may be a better conductor
Concrete is not a good insulator as it has high thermal conductivity, meaning it can transfer heat easily. This is why concrete is used in buildings to store heat rather than insulate against it.
No, concrete is not a good insulator for buildings and structures. It has high thermal conductivity, meaning it does not effectively prevent the transfer of heat.
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
a good insulator of heat keeps the heat in, so you stay warm
a good insulator of heat keeps the heat in, so you stay warm
insulator is a object that is not a good conductorSo it keeps the heat in.
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.
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
A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
No, zinc is not a good insulator. It is actually a good conductor of electricity and heat.
no i think i am right ( i hope )
No because it is a good conductor of heat and electricity!
