Specific Heat Vs Heat Capacity
Specific Heat Vs Heat Capacity. What is the difference between specific heat capacity, heat capacity, and molar heat capacity 164,843 views sep 21, 2017 this chemistry video tutorial explains the difference. Specific heat (c) is the amount of heat required to change the temperature of a mass unit of a substance by one degree.
These two kinds of energy are essential to our daily lives regardless of whether they come in the form heat or light. How heat is transferred between one object and another depends on the type of material it is made of and the environment in that it's placed. There are three main types of heat transfer: convection, radiation, and energy transfer.
Energy transferEnergy transfer, in general is the exchange or movement of energy between two or more entities. It is possible to transfer energy from one location to another, or between two objects. Energy transfer can happen for a number of reasons. They may take place to warm an object or transmit energy to the surroundings. This is an essential process for the existence of life on Earth.
Two methods of energy transferred are through conduction and radiation. Conduction is an effective method of transferring heat within metals. A good example is that the handle of a steel spoon will conduct heat well. If the spoon is heated, the handle heats up.
Radiation, which is a form of energy transfer, is vital to the survival of life on Earth. When a fire is burning then a significant amount of energy is transferred into the airthat travels at a high speed. This energy travels across all directions.
Latent and sensible heatThe energy moves through space regardless of whether it's latent or sensual heat. It is based on the temperature of your air. It can be caused by direct conduction of the transfer of energy between two materials. An example of this is the energy needed for water to warm up or get cool.
Sensible heat refers to the quantity of energy required to change the phase of a substance. There are a variety of scenarios in which sensible heat may be needed to cool or heat water.
Latent and sensible heat are the two major elements of a climate system. They are important in climate, weather, and oceanic processes.
Latent and sensible heat may be assisted by the water vapor in the atmosphere. Water vapor is a greenhouse gases and is a key factor in cloud formation. It is a gas that rises in the atmosphere to form clouds. Water vapor in the atmosphere condenses and releases its heat stored in it when it is no longer possible to hold any more.
ConductionConduction is the process of heat transfer. Conduction of heat is among the most popular ways to transfer heat.
Conduction is the transfer of heat between a liquid, solid or gas. It is influenced by temperature and distance traveled with the length of the journey and the properties of the material. The primary element of conduction is the thermal conductivity. It's the ability of a material to transfer heat energy. The units that determine thermal conductivity are W m-1 K-1.
The thermal conductivity of a substance is measured by the speed of electrons that travel from atom to. It also evaluates how the substance conducts electric current. Objects with high thermal conductivity are able to be more efficient at handling heat than other objects. Objects with low thermal conductivity can be thought of as insulation.
ConvectionIf you're cooling or heating convection heat is one of the most effective methods of transferring energy. Convection heat transfer depends on many aspects, including the form of the fluid and its flow speed. It is important that you remember that the rate that convection heat gets transferred is proportional to the variation in temperature of the fluid.
The first law of thermodynamics states that heat loss rate is dependent on temperature. This means that a hot object loses heat faster than one that is cold. Here's an example to illustrate this concept: Let's say you have a glass filled with hot water and red food dye. As the water cools down the dye will begin to set and the liquid will become transparent.
RadiationIn the form of heat or light, radiation is an ubiquitous phenomenon. Thermal radiation is, in its most basic form, the release of heat from particles made of matter. It could be warm or cold. It can also be described as electromagnetic waves generated by matter in the most advanced forms. In some instances, the wavelengths of thermal radiation can be correlated to the temperature. The infrared spectrum is the area where radiation related to heat is most prevalent. Infrared cameras can detect it. Convection is an excellent example of conduction of heat. It's also a sign of the heat-related Chemistry.
It is easier to see the magnitude of thermal radiation by studying its spectral components in the context a total amount of matter. If there is no equivalent volume, it could be considered an unidentified black hole.
