Tell me about thermal runaway reactions

Topic: Heat

Question

September 24, 2012

Sir, I was wondering if you might write a page / tell me about thermal runaway reactions?

- UK

22947

Answer

A thermal runaway reaction is one where the chemical, atomic or electrical event feeds back on itself, thus increasing to the danger point.

In chemistry, thermal runaway when an exothermic reaction goes out of control, often resulting in an unwanted explosion.

In an atomic reactor, thermal runaway is most often caused by failure of the reactor vessel's cooling system.

I will try to add more material on the subject on the website soon.

Insulating the roof

Topic: Thermal Insulation

Question

August 30, 2012

plz can you information about
1 how will be complete process to thermal insulation of roof?
2 which materials we can used?
3 what is the advantage ?

Rakesh - India

Answer

On the outside of the roof, materials need to resist and protect from rain and insulate from outside heat. Asphalt roofing insulates from the cold, but it gets hot in the sun.

Inside the roof, you should have layers of loose insulation. Some use paper or cotton products, but they must be made fire resistant.

Good insulation inside the roof can reduce the house temperature in the summer and keep in heat in the winter.

Need to make glove that insulates heat

Topic: Thermal Insulation

Question

August 28, 2012

Hallo. I am in grade 7 and we have to make a glove that will insulate heat. Any ideas?

Thanks

Answer

A glove that a person wears in cold weather usually is made of several layers of insulating material such as wool or cotton. Likewise a similar type glove can insulate and protect you from heat.

Holding a liquid at 530 degrees F

Topic: Heat Transfer with Hot Coffee

Question

June 20, 2012

Hello,
wondering if you know what type of cup, styrofoam, paper, or cardboard (like an oatmeal container) cup would hold a liquid of 530 degrees farenheit with out breaking down. You know hold that temperature till the liquid cooled on its own. Not concerned about keeping the heat, just want to know what type of material will hold up to that temperature with out breaking down at all.

Many thanks!

Answer

Paper and cardboard products ignite at around 450 deg F. Styrofoam starts to melt at 460F.

It might be best to use a metal container.

How does mass affect thermal energy?

Topic: Thermal Energy

Question

April 26, 2012

How does mass affect thermal energy?

- Canada

22613

Answer

The thermal energy of an object is the total kinetic energy of all its atoms and molecules. Increasing the mass can increase the total thermal energy provided that mass is at the same or greater temperature as the original object.

Wants to use greenhouse illustrations

Topic: Heating a Greenhouse

Question

November 30, 2011

Good afternoon Mr. Kurtus,

I work at Oxbow Meadows Environmental Learning Center in Columbus, Georgia. I'm trying to make some interpretative signs for our gardens one of which is on how a greenhouse works. I was wondering if you would grant me permission to use your greenhouse illustrations for an educational sign here at the center?

Thank you for your consideration.

Sincerely,
Alicia Garcia
Staff Naturalist

Answer

Yes, feel free to use the illustrations.

Best wishes with your Environmental Learning Center. Let us know about the goals and progress of the center.

Why doesn't the temperature get in equlibrium with the Sun?

Topic: Heat

Question

November 5, 2011

sir i have a question ,why temperature of not get equlibrium with sun?

owais - Pakistan

22141

Answer

Although the Sun heats the Earth, much of its radiation is reflected--especially from the oceans. Of the energy that does heat the Earth, a part of it is re-radiating in to space. These two factors keep the Earth from not becoming in thermal equilibrium with the Sun.

Does heat trasnfer through a wall?

Topic: Heat Transfer

Question

November 2, 2011

How Do You Say That Heat Cant Transfer through a wall????

Mj - USA

22128

Answer

Heat does transfer through walls. However, walls are constructed of materials that usually transfer heat very slowly, such that it is not noticeable. It takes a long time for heat or cold to transfer through a thick concrete wall. Air gaps an insulation also are used to slow down and diminish the heat transfer.

Answer

I can't tell which company is the best, but for a listing, see: Solar Home Systems.

A good article on solar energy for the home in India is Solar Energy for Home Electricity, not enough?.
