    Determination of specific heat Capacity of a solid by electrical method Introduction Thermal conductivity heat is transferred as a consequence of temperature difference between 2 bodies, heat energy passes form a hotter to the colder body. Specific heat capacity is the amount of heat energy required in joules to raise 1kg of a substance by 1 degree Celsius, different substances absorb heat energy at different rates not all substances require the same amount of heat energy to increase the

  • Investigating Specific Heat As A Function Of Temp

    THE LATENT HEAT CALORIMETER The specific heats of various solid samples were measured Investigate specific heat as a function of temp 1. INTRODUCTION uses for latent heat, meteroreology, and specific heat, cooking pans The specific heat capacity is defined as the amount of energy required to raise a substance by a temperature… tippler?. It is a fundamental property of materials and thus its determination has been given great importance throughout history. Prior to thermodynamic research

  • Specific Heat Lab

    524 Words  | 3 Pages

    the purpose of this lab was to find heat capacity and to calculate the specific heat. A calorimeter is an apparatus for measuring the amount of heat that is involved with chemical reaction or in any other process. We tried to do our plan and figure out how we are going to do this lab We got a stirafoam cup and put water in it and heated it up to make room temperature water. Grab the aluminum and tie it onto the string. We grabbed a probe and put it inside of our calculator and took the temperature

  • Specific Heat Capacities Of Metals

    1630 Words  | 7 Pages

    Specific Heat Capacities of Metals Aim: The aim of this experiment is to determine the properties of two unknown metals by heating them up to their initial temperature and then determining their specific heat capacity by calculating the temperature difference once it reaches equilibrium with a room temperature water bath. Therefore comparing the two metals with their specific heat capacities on a known table and deducing the unknown metals. The water bath needs to be well insulated so that no heat

  • Specific Heat Capacity of Water (DCP and CE)

    1209 Words  | 5 Pages

    Aim: To determine the specific heat capacity of water by heating water and recording temperatures at regular intervals. Hypothesis: (i) P = Q /t (ii) Q = m c ΔT Where, P is the power of the heater Q is the total energy provided by the heater t is the total time for which the heater was used m is the mass of water c is the specific heat capacity of water, and ΔT is the change in temperature From (i) and (ii) m cΔT = P t ΔT = (P/mc) * t This is in the form y = mx +

  • The Effect Of Chemical Reactions On Temperature, Enthalpy, And Specific Heat

    tested the amount of change in heat given off during different chemical reactions. We created a calorimeter that we will use to test different reactions to see how the heat energy was affected. After completing the experiments we were able to tell what chemicals or metals would change the heat energy for every reaction we tested. Overall, this experiment showed us what characteristics of chemical reactions affect the change in temperature, enthalpy, and specific heat. Discussion of Results During

  • Discuss Why Hydrogen Bonding Is Essential for Life

    every 10C below optimum temperature, the rate of successive substrate-enzyme collisions decreases by 2 to 3 times [Campbell and Reece, p862]. High specific heat capacity also benefits marine environments by resisting temperature fluctuations, which is perhaps why marine food chains are often many times longer than those of terrestrial organisms. The high heat capacity of water is one of several hydrogen-bonding attributes that benefit the marine environments, unsurprisingly, with the high surface tension

    water and its importance 3. High specific heat capacity The amount of heat required to raise the temperature of 1 g of water by 1oC Water has a high specific heat capacity A lot of energy is required to increase the temperature of water to 1oC due to the hydrogen bonds ~ heat must be absorbed in order to break hydrogen bonds & heat is released when hydrogen bonds form. Learning Outcomes : (b) Describe the properties of water and its importance 3. High specific heat capacity Water provides a very

  • The Biological Significance Of The Properties Of Water Essay

    water molecules water is given the following properties relating to heat and temperature :- 1. Relatively high heat capacity 2. Relatively large latent heat of vaporisation 3. Relatively large latent heat of fusion These three properties are very similar and basically mean that a relatively large amount of energy required to change the temperature or state of water. The specific heat capacity of water is 4184J/kg, over 40 times that of sodium chloride. This

    Introduction/Purpose To determine whether boiling point, density, mass, and volume are intensive or extensive properties two experiments will be conducted. One experiment will be dedicated to identify if boiling point is an intensive or extensive property by boiling water at different quantities. The other experiment will identify if density and mass are intensive or extensive properties by utilizing a grape. The experiment will consist of measuring the mass and volume of a grape to determine the
