¶ … Heat and Temperature
Although there is a difference between heat and temperature, the correlation which exists between them is very significant (Campbell, 2009). Temperature is the degree of vibration of particles in a system. High temperature therefore implies a high degree of vibration of particles. Heat is a type of energy which is usually changed into kinetic energy. As long as an object is heated, its temperature will increase. While heat is a form of energy, temperature is the effect of heat (Campbell, 2009). Intrinsically, the relationship between heat and the temperature is associated with change in the state, from solid to liquid and then gas.
Convection and conduction
Convection as a process involves the transfer of heat is from one region to another by actual motion of matter (Convection, 2013). Therefore, convection is only possible in fluids. In convection, temperature differences in the fluids drive currents. When fluids are heated, they expand, lowering the densities of the heated material. This causes the heated fluid to rise through the cooler fluids. Convection can either be natural or forced. Natural convection involves the force of gravity (Convection, 2013). When fluids are heated from below, the hot parts expand becoming less dense. Because of this, the hot fluid rise and replaces the less hot fluid above. The less hot fluid above is forced down as it is denser. It again gets heated and rises up. This process is continuous, and it creates uniformity in temperature of the fluid. In forced convection, materials are forced to move up by physical...
This condition slows down the heating process and also because of convection currents. Land and water have different capacities for absorbing and liberating heat. It is good to note that the specific heat of water is higher than that of land. Hence, water requires more heat than land does to increase its temperature at the same number of degrees. Water, having a higher specific heat, warms up more slowly
(Wolverine Tube Heat Transfer Data Book, 2009) Basic components of Shell and Tube Heat Exchangers include the following basic components although there is a plethora of existing specific features used in design of the Shell and Heat Tube Exchanger. The components specifically are: (1) Tubes -- "...the basic component of the shell and tube exchanger, providing the heat transfer surface between one fluid flowing inside the tube and the other fluid
The Temperature in my Hometown: Data For example, Clifton Heights, Pennsylvania, showed a great variety in temperature over the course of August 2005. The actual high temperature in degrees Fahrenheit was 97, and the low 63. The normal highs and lows in the month of August in Clifton heights are 88 and 66. This fluctuation means that on very hot days, stores would find it difficult to cool their interiors in
Physical Science: Heat It is reasonable to suggest that just about everyone has felt the warmth of the sun or warmed themselves by a fireside, but many people may not understand the source of the energy they are feeling, particularly at the molecular level. Without heat, though, humankind would soon cease to exist and the universe would quickly collapse into an absolute zero nothingness. To gain some further insights into this
temperature and answer questions about this force. Temperature and heat are two different issues. Temperature is how cold or hot air, water or an object is. Heat is the energy which is produced when molecules and atoms are in motion. The amount of energy an object may hold is determined by its shape and size. The main difference between the Kelvin and Celsius scale is Kelvin is used mainly by scientists, while
Hypothermia Treatment Using Radiant Heat Hypothermia Critique of Postoperative Hypothermia Treatment Using Radiant Heat by Yang et al. (2012) Critique of Postoperative Hypothermia Treatment Using Radiant Heat by Yang et al. (2012) Perioperative hypothermia has been shown to increase the risk of post-surgery complications, thereby threatening the health of patients and increasing the cost of care (reviewed by Hooper et al., 2009). Guidelines for active warming measures have been suggested by a number of
