The paper tells that a mass of a given metal block got weighed then a piece of twine like 30 cm long became attached to it. Then the block became lowered into a steam boiler. The boiler then had half filled water. As the water got heated to boil, the mass of an empty calorimeter got measured. The calorimeter got filled two-thirds with water that was several degrees colder compared to room temperature. Then the mass of both water and calorimeter became measured. In the experiment, an outer cap became placed around the calorimeter to prevent heat loss from it when it becomes warmer than room temperature. In the experiment, the two metals used became copper and Iron. The mass of copper and iron became 269.53g and 230.80g respectively upon weighing. The mass of calorimeter used became 46.13g. The mass of calorimeter added water for Iron was slightly more than that of copper. In starting with an original temperature for the calorimeter plus water at 21.9 degrees, in dipping the blocks of metal, the final temperature dipped with copper became 30.4 degrees while for iron became 30.1 degrees. In calculating the specific heat of solid for the two experiments, an error of 0.006cal/g-degrees became found for copper while an error of 0.003cal/g-degrees became recorded for Iron. Therefore, iron recorded a percentage error of 2.86% from the accepted value while copper recorded a percentage error of 6.45%.

The paper presents the experiment that uses heat loss plus heat gain of some substance and also the phenomenon of specific heat in the laboratory. It will also compute specific heat from other substances and then compared it to actual values…
Heat is simply just one of those types of films; the kind that gets under your skin and flows all the way through your body like a drug. Set in Los Angeles, and packed with well-rounded characters troubled by their own past, Heat is a superior film which is sexy, stylish, atmospheric and includes an abundance of action.
The objective of the experiment is to find out the specific heat capacity of water by monitoring change in temperature of a water that is heated to boiling under constant time interval.
The specific heat of any material determines the amount of energy needed to heat 1 kg of
Sometimes the media is separated by a wall such that the fluids do not mix or get into direct contact. Heat exchangers have a broad area of use example being in ventilation, air conditioning, and space heating. As the fluid passes through the exchanger it either lose or absorb heat due to latent heat.
In the distillation column, separation of air happens in its liquid rather than its gaseous state. Distillation, which is the separation of liquid or vapor mixture into its component fractions of desired purity by heat application or
The heat capacity is the amount of heat energy required to raise the temperature of a unit mass of an object by one degree. The specific heat capacity is the amount of heat energy needed to raise the temperature of one gram of material by one degree. Two objects
rred to as thermal capacity, is defined as the amount or quantity of heat or thermal energy needed to raise a body’s temperature by a single unit of temperature (Hewitt, Suchocki, & Hewitt, 2012). Thus:
According to Hewitt et al. (2012), two factors determine the heat
Heat transfer through the circuits is through the metal plates and gasket which have holes for both hot and cold water to pass. The number of plates is proportional to heat transfer, but reduces the flow rate. Flow disturbers in the
It is the transfer of heat through electromagnetic waves. Material releases thermal energy in which is absorbed by another material. Radiation emitted by surfaces is given by Qemit = εσAsTs4 (Supuk, 2014).
Moreover, this experiment aims to find out the temperature efficiency for co-current and counter current, the concurrent and the counter current operation overall heat transfer coefficient, the number of transfer units and the
