How much pressure can create one joules of heat?
Almost unlimited. Pressure is force divided by area; if the heat is applied in a very small area (small volume), even a small amount of heat can cause a tremendous pressure.
Sulfur a good conductor of heat?
No, sulphur is not a good conductor of heat its crystals may conduct a very small amount of heat.
In what area or organ of the human body is heat created?
Heat is created in every cell in the human body. It is a by-product of our metabolism. We only obtain about 40% of the energy contained in the food we eat. The other 60% is lost as heat.
How the surface area to the volume ratio affects heat loss?
The bigger surface area to volume, the quicker it will lose heat, as it has a bigger surface where the heat can rise and travel out from. If the volume is the same but the surface area is smaller, heat will stay in for longer as there is only a small area for the heat to escape from, meaning it has to go little by little.
Does the surface area of a can affect boiling water?
the pan itself must heat up and transfer heat to the water. Larger pan requires more heat. Different metals for the pan will require a different amount of heat and probably also effects heat transfer by conduction. thru the pan.

Material that doesnt allow heat to be conducted easily?
A thermal insulator. The best is a vacuum, but static air is good, if it can be contained in a mat of fibres for example.
What are some ways to heat a room with a fire?
Contained, or wild fire there is going to be a lot of heat .
What are small itchy bumps on and around butt area they won't go away At first they appear to be pimples or bites They do not spread and itching is not continuous but when it itches it is intense?
Might be heat rash - if you've been sweating or in hot conditions, this is a common area to get heat rash. Your description of the small bumps are consistant with heat rash.
Why are rough surfaces good emitter of heat?
A rough surface has more surface area which allows more heat to be transferred.
Why is heat a good insulator?
the space between atom of crystals is too much small therefore it can not absorb heat. Halim orakzai
Does a larger roof have greater heat loss than a smaller roof?
If a large roof is twice the area of a small roof and they are otherwise the same, the heat loss will be approximately double. If the large roof is twice as insulated as the small roof the heat loss will be similar.
