Well, let's think about that:
The effect of the fire in a regular oven, gas or electric, is to cause heat to collect
on the outside of the food. The heat then spreads throughout the food and cooks it.
The effect of the radio waves in a microwave oven is to cause heat to appear on
the inside of the food. The heat then spreads throughout the food and cooks it.
If you're following a recipe for a cake, and it says that the cake needs to bake
for 30 minutes, do you think you could achieve the same result by baking it
1 minute a day for a month ?
No. The unequal heating will produce breezes, and perhaps clouds and rain, but much more is required to produce a tornado.
because of its covering.
Iron oxide can be reduced by heating with carbon to produce reddish brown iron solids.
Heating a wood splinter will lead to combustion, resulting in the release of smoke, ash, and gases due to the breakdown of the organic material. On the other hand, heating glass tubing will not combust; instead, it undergoes physical changes, such as expansion or contraction, depending on the temperature change. Glass may also soften or melt depending on the temperature, but it will not produce combustion byproducts like wood.
Heating can be due to a chemical change, for example burning a fuel is in effect a chemical reaction with oxygen. Also some chemical reactions are exothermic, ie they produce heat. Not so many produce cooling, but one is the combination of ice and salt.However heating and cooling happen for other reasons as well, so you can't say they are examples of chemical changes. It is correct to say that some chemical changes result in heating and cooling.
No answer exists. Any 2 consecutive numbers will produce an odd sum.
No. The whole idea of a home heating system is to produce heat, not to produce work.
The two 5kW heating elements will produce a total of 10kW of heat when energized simultaneously.
Heating is the process of increasing the temperature of a substance without causing it to chemically change. Burning, on the other hand, is a chemical reaction where a substance combines with oxygen to produce heat, light, and usually ash or smoke as byproducts.
No. The unequal heating will produce breezes, and perhaps clouds and rain, but much more is required to produce a tornado.
Chemical energy will produce the light in a firefly, or in a hand-held glow tube. Electrical energy will produce the light in a light bulb. Heating something up to a high enough temperature will produce light. Burning a material may produce light.

Depends what you heating source is. Generally no.. If you want to see sparks from heating a metal use Magnesium.
Forces can produce motion, change in shape or size, and heating or cooling effects in an object.
Solar heating systems utilize solar panels to absorb sunlight and convert it into heat energy. The sun's rays are absorbed by the panels, which then transfer the heat to a liquid circulating within the system. This heated liquid is then used to provide warmth for residential or commercial buildings.
Infrared radiation from the sun produces a heating effect on the Earth's surface. This radiation is responsible for warming the planet and heating objects on the surface.
A microwave bacon cooker is designed to produce crisp bacon. It may not taste as good as stove-top fried bacon, but it will come out crispier with a cooker than by just microwaving bacon on a plate.
