Heat as another form of energy is called thermal energy. When you place your kettle of cold water on a gas cooker or a heating stove, after some time, the water tends to feel hotter to touch. Hence, you infer that heat has been transferred from your gas cooker or heating stove to the cold water.

It is a general fact that heat commonly flows from a hot object to a cold one. Therefore when we place in contact with a cold object, a hot always warms the cold object. Never does the reverse occur.

A cold object can never warm a hot object. What does the work of heating the cold object is the heat energy that flows from a hot object to a cooler one due to their temperature difference.

EFFECTS OF HEATS

Heat can have several effects on an
object. These effects include;

1. Temperature change of the body
   The temperature of the body changes as soon as heat is added to the body, thus raising the temperature of the body.

2. Change of state of the body

Heat can alter the state of a body. The application of heat will change the state of the body. For instance, a body in the form of a solid can change its state when heat is applied to it. ice as an example of a body in a solid-state will melt to liquid when heat is added. If a greater quantity of heat is applied to the liquid, it will vaporize or change from liquid to vapor state.

1. Expansion of the body.
   When heat is applied to a solid body, the body will expand. And when the body expands, the dimension tends to increase as well.

2. Change in the physical properties of a body.
   The addition of heat to a body may cause changes in the electrical resistance, magnetic properties, conductivity, electricity, density, and color of a body.

3. Thermionic emission
   Electrons seem to be emitted from the surface whenever heat is added to a metal. This process is known as Thermionic emission.

4. Chemical change
   When heat is added to a body, it may affect changes in the chemical properties of a body.

5. Change in Pressure
   The application of heat to gas will cause an increase in the pressure of the gas, so also is its volume.

Who Am I?

_{I am just a beginner who lives in the Western Hemisphere of Africa with his parents. My name is James but you can notify me with @churchangel, here.😂 Being the first child, My parents, Mr. and Mrs. Onu who are just wonderful And hardworking couples. My father is an electrical engineer while my mother is a trader. They always work collaboratively just to make sure that their children don't lack the necessities. I graduated from high school in the year 2018. And My favorite subjects are physics chemistry and biology. I am going to enter the university because my goal is to study these subjects in the future and to become a respected professional in one of the fields. Between, I am an accomplished computer hardware technician. After I obtained my SSCE certificate, I took interest in learning more about computer hardware and its maintenance. I am obsessed with all tech-related and I enjoy using my skill to contribute to the exciting technological advances. I'd spend my free time learning about programming and also assisting people on how to fix any problem related to Tech! 💞*********🌹❤️Special thanks to my supporters❤️🌹********💞 At this very moment, I am unable to find a suitable words to express my gratitude over all your supports. You guys generosity never ceases to amaze me. This space has become a place of fun for me. All because of colleagues like you. Thanks for being there for me. I will always appreciate all your kindness and supports towards me and my family💕.}
