yes it will cool down slower as the heat cannot get to the water as easily

What factors affect the rate of heat transfer by conduction?
The thermal efficiency (insulation U factor) of the material through which the heat is conducted, and the number of films (each surface to surface contact of similar or dissimilar materials is a film) through which the heat passes are what affect rates of transfer of heat by conduction. Metals as opposed to non metallic elements have a higher rate of heat transfer. Without citing formulas: Film insulating is the most effective means of insulating an object from heat. Layers of thin materials can be better insulators than thick materials that are not layered. If the layers are dissimilar materials from one film to the next the insulation is even more effective. Air is one of the most effective insulating materials if it is trapped between layers to prevent motion from convection. *When factoring in radiant or convective heat transfers to conductive heat transfer the surface between the heat source and the insulator is counted as the first film.
What is the formula for critical number of layers?
Please clarify.
How does thermal insulation affect energy?
I am assuming you mean "how does it affect energy use". Heat is energy, the kinetic (moving) energy of the atoms in a substance. The hotter the temperature, the faster the atoms or molecules are moving. Heat energy moves via a number of mechanisms from high temperatures to low temperatures. Thermal insulation doesn't change the energy, or temperature of an object, it merely slows the rate of movement between the object and its surroundings. Polished bright metals can lower the transfer of energy via radiation. Small pockets of unmoving air (like in foam or fiberglass) can slow the transfer of energy by convection. Other materials, like paper or some plastics, conduct heat poorly. So thermal insulation can help keep hot things hotter, longer or cold things colder longer than without insulation. Or put another way, it takes less energy to maintain an insulated object at a given temperature than without insulation.
Does insulation rated R-35 allow more heat to pass through than insulation rated R-1?
Just the opposite. Like the 'SPF' of suntan lotion, and like the resistance ofan electrical component, the higher number allows less to soak through.
Do the number of particles in an object affect its thermal energy but not its temperature?
TRUE
What would the most efficient number of insulation layers be?
It is not simply a question of the number of layers but the properties of each layer.
Why insulation resistance is given in mega ohm?
If it were less than a number of Megohms it would not be insulation.
Are the new ski jackets warm?
Depends on if you buy an insulated or shell ski jacket. Insulated jackets have built in insulation and some jackets like 3 -n-1 jackets the insulation you can zip out. Insulation is measured in grams and the higher the number the warmer the coat is. Shell ski jackets just have an outer waterproof breathable layer with no insulation. Most people layer up with Shell jackets and shed the layers if they get too warm. If you get hot easily then Shell ski jackets are for you and they also give you more mobility.

What is Number of tissue layers developing in the embryo?
Three layers develop in an embryo .
Where can one purchase insulation batts?
One can purchase insulation batts from a number of different places. Generally, Home Depot is a good store that has a wide selection of insulation batts to choose from.
Where can someone buy reflective foil insulation?
Someone can buy reflective foil insulation from a number of companies such as Amazon. Amazon has a large selection of reflective foil insulation from various manufacturers.
If you fold a piece of paper 50 times how many layers will there be?
Each time you fold paper, the number of layers is doubled.0 folds = 1 layer (original sheet) = 201 fold = 2 layers = 212 folds = 4 layers = 223 folds = 8 layers. = 23...etc, all the way to 50 folds. In other words, the number of layers increases exponentially.Following the pattern, If you could fold paper 50 times, the number of layers would equal:250 or 1,125,899,906,842,624 layers.
Do the number of seeds in a flower pot affect how quickly they germinate?
No, it shouldn't. It may cause some of the seeds not to germinate as they fight for sunlight, but it shouldn't slow them down.
How effective is cellulose insulation?
Cellulose is considered to be as effective as fibreglass insulation. It has a number of advantages - it is environmentally friendly as it does not require chemical synthesis and is relatively cheap.
