Heat can be generated in many ways- friction, chemical action, electrical resistance, solar energy, etc. Fire is quick and easy, but if you have an electric stove or microwave, you use a non-fire heating process all the time.
if we add concentrated sulphuric acid slowly in water,the reaction of concentrated sulphuric acid with water produces heat and thus the water will be heated.
solar energy
In most cases, heat. It is proven that water absorbs heat - this is how water balloons can withstand relatively high heat levels. This is also how humans can walk on burning coals without being burnt because we are around 73% water.
Use a thermocouple.
There are various ways that a fire can be started without using a flame. Many chemical reactions produce enough heat to start a fire. One example is the mixture popularly known as "negative x". This mixture, which consists of ammonium chloride, ammonium nitrate, and zinc powder, will burn when exposed to a drop of water.
The old saying "there is no smoke without fire" tells you the whole story really. The formula is: FIRE + SMOKE ------> BURNING + HEAT That's all there is to it.
Put water in boil half heat out salt and hot sauce in it and place it on your hair with gloves.
You can expose the metal to hot water or oil.
Without heat from the sun the water cycle would not work .
using a fire place.
fire
Yes it will. This is because cold water has less heat than hot water and therefore can absorb more heat when put on the fire.
Cooking is basically the application of heat to a food for a certain amount of time. Fire provides the heat and water helps to spread that heat evenly across the surface of the food.
