Temperature is related to the kinetic energies of the molecules of a material. It is the average kinetic energy of individual molecules. Internal energy refers to the total energy of all the molecules within the object.

What is the kinetic theory of gases?

The behavior of the system is well described by kinetic theory of gases. Kinetic theory is based on the fact that during an elastic collision between a molecule with high kinetic energy and one with low kinetic energy, part of energy will transfer to the molecule of lower kinetic energy.

How does heat transfer occur?

Heat transfer occurs by conduction or by thermal radiation. When the flow of heat stops, they are said to be at the same temperature. They are then said to be in thermal equilibrium . As with work, the amount of heat transferred depends upon the path and not simply on the initial and final conditions of the system.

Heat is a form of energy, but it is energy in transit. Heat is not a property of a system. However, the transfer of energy as heat occurs at the molecular level as a result of a temperature difference.

What is heat energy?

Definition of Heat Energy. Heat has always been a mystery. Antoine Lavoisier theorized that heat was a substance with mass. That meant that heat transfer involved the transfer of an actual substance between bodies. Unfortunately, Lavoisier's theory was not supported by experimental observation, so a better description of heat was needed.

What is the measure of temperature?

Temperature is a quantitative measure of hotness or coldness. Solids, liquids, and gases are made up of atoms and molecules. When these atoms and molecules are moving slowly, then the temperature of that substance would be low. The faster the atoms and molecules move, the higher the temperature. Heat is the total energy ...

How does heat transfer energy?

Heat can be transferred by conduction, convection, and radiation.

What is the direction of heat transfer?

Heat transfer is when heat energy flows from the object of higher temperature to an object with a lower temperature. It will never do the reverse. Heat energy can be transferred by the following methods: conduction, convection, and radiation.

How does conduction transfer heat?

Let's first look at the process of heat transfer by conduction. Consider the following situation, which you may have experienced. You have a cup of very hot coffee, and you put sugar into the coffee and use a spoon to stir the coffee. You accidentally left the spoon in the coffee when you left it on your table. Minutes later, you grab the spoon from the coffee and notice the spoon is now hot. The spoon, which was initially cold, is now nearly as hot as the coffee. This situation is an illustration of conduction. The molecules of the spoon immersed in the coffee were forced to move faster. These faster moving molecules bump into adjacent slower moving molecules and cause them to move faster, etc. After some time, all of the spoon molecules will be moving faster. Conduction is a process of heat transfer where the faster moving molecules impart their energy to slower moving molecules until the entire substance is moving with a faster speed. The figure you're looking at onscreen illustrates conduction.

What are the two types of convection?

There are two types of convection, and they are: Natural convection. Forced convection. Natural convection: When convection takes place due to buoyant force as there is a difference in densities caused by the difference in temperatures it is known as natural convection.

Why does land lose heat?

The land quickly loses heat when compared to water due to the differences in heat capacity. Consequently, the temperature of the sea is relatively higher, which creates low air pressure there. This sets up a flow of cool breeze offshore, known as the land breeze.

What is the process of heat transfer in fluids?

Convection is the process of heat transfer in fluids by the actual motion of matter. It happens in liquids and gases. It may be natural or forced. It involves a bulk transfer of portions of the fluid.

What are some examples of natural convection?

Examples of natural convection are oceanic winds. Forced convection: When external sources such as fans and pumps are used for creating induced convection, it is known as forced convection. Examples of forced convection are using water heaters or geysers for instant heating of water and using a fan on a hot summer day.

Is convection natural or forced?

As we have read previously, convection can either be forced or natural. One of the most common examples of natural convection is the phenomena of the sea and land breeze. Sea breeze: This phenomenon occurs during the day. The sun heats up both the sea surface and land.
