Heat+and+temperature

Hi! This is heat and temperature. Often, the concepts of heat and temperature are thought to be the same, but they are not.The concepts are sometimes thought to be the same because people think that the more the heat, the more the temperature. However, that is wrong, although it may sound reasonable. Here is more about heat: Heat is energy. The motion of atoms and molecules creates a form of energy called heat or thermal energy which is present in all matter. In fact, even in the coldest voids of space, matter still has a very small but measurable amount of heat in it! Many different types of energy can be converted into heat energy. Light, nuclear, sound and thermal energy can cause a substance to heat up by increasing the speed of its molecules. So, just put energy into a system and it heats up. Take the energy away and the system cools down. Here is more about temperature: Temperature is a measure of the average heat or thermal energy of the particles in a substance. As it is an average measurement, the temperature does not depend on the number of particles in an object. For instance, the temperature of a small cup of ice water has the same temperature as a jug of ice water, even if the jug of water has millions and millions more water molecules in it. We experience temperature everyday. When we boil water, we wait for the temperature of the water to increase and when we are making ice-cream we wait for the temperature to decrease. When we have a fever or when we stand in the sun, we feel hot and likewise, when it is snowing we will feel cold. I will tell more if I there is time.

Hello everybody! Heat = Sun, Fire, etc. Heat is a source of energy! WIthout heat, the surroundings arround us would all be ice and all living things would die! Heat keeps us warm and hels us in many things in our daily life. Heat can help us boil water, cook food, warm us, and many other ways. The sun is our main source of heat.Burning fuels and friction can also produce heat. Heat can also be produced by electrical appliances,like ovens, stove, water heaters and others! Temperaure= WE all can measure our temperature. WE can use a clinical thermomether(Centigrade) to measure our temperature when we are not feeling well and and another type of thermomether which is called the laboratory thermomether(Fareinheit)to measure temperatures when doing experiments. Thermomether has a liquid inside called as mercury. When we read temperature we must read the it at eye level to see the temperature accurately. Temperature starts from hot to cold. Example when a glass of hot water. The cup of glass water's temperature will decrease and will be at room temperature. WE experience heat and temperature everyday in our daily lifes. I will tell you more about heat and temperature the next time...
