How do you find the specific heat capacity of an experiment?

  1. Place an electrical immersion heater into the central hole at the top of the weighed metal block.
  2. Connect the heat in series with an ammeter and in parallel with a voltmeter.
  3. Place the thermometer into the smaller hole.
  4. Insulate the block by wrapping it with cotton wool.
  5. Record the temperature of the block.

How do you create a practical specific heat capacity?

What is specific heat capacity a level physics?

The amount of thermal energy required to raise the temperature of 1 kg of a substance by 1 °C. This quantity determines the amount of energy needed to change the temperature of a substance.

How do you find specific heat capacity in physics?

What is the conclusion of specific heat capacity?

Conclusion: The specific heat capacity of Alumium is 900J/Kg/K and the specific heat capacity of Lead is 1300J/Kg/K. This is as I predicted. This means that it takes more energy to change the temperature of lead than of Aluminium.

How do you determine the specific heat capacity of a material?

  1. ΔE = change in thermal energy, in joules (J)
  2. m = mass, in kilograms (kg)
  3. c = specific heat capacity, in joules per kilogram per degree Celsius (J/kg °C)
  4. Δθ = change in temperature, in degrees Celsius (°C)

How do you investigate specific heat capacity of water?

  1. Place one litre (1 kg) of water in the calorimeter.
  2. Place the immersion heater into the central hole at the top of the calorimeter.
  3. Clamp the thermometer into the smaller hole with the stirrer next to it.
  4. Fully insulate the calorimeter by wrapping it loosely with cotton wool.
  5. Record the temperature of the water.

How do you calculate specific heat capacity in a school science lab?

What are the sources of error in specific heat capacity experiment?

Loss of heat by conduction is the main cause of error in this experiment.

What is Q MC △ T?

The amount of heat gained or lost by a sample (q) can be calculated using the equation q = mcΔT, where m is the mass of the sample, c is the specific heat, and ΔT is the temperature change.

Does specific heat capacity depend on temperature?

Therefore specific heat does not depend on temperature.

Why is specific heat capacity important?

Specific heat capacity is a measure of the amount of heat energy required to change the temperature of 1 kg of a material by 1 K. Hence it is important as it will give an indication of how much energy will be required to heat or cool an object of a given mass by a given amount.

How do you calculate specific heat example?

How do you calculate the specific heat capacity of a graph?

How do you find the specific heat of an unknown metal?

What is the specific heat capacity method?

The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of one kilogram of the substance by one degree Celsius.

How is specific heat capacity used in everyday life?

High specific heat materials can be used as insulators. Wood, for example, has high specific heat. During the summer, wooden houses will keep the inside cooler. Builders can select appropriate building materials based on location and altitude.

What is the conclusion of calorimetry?

4 CONCLUSIONS The very great advantage of calorimetry is that it is completely non-specific, which means that almost any type of biological reaction or process may be measurable with calorimetry. The limit may be the sensitivity of the instrument.

What factors affect specific heat capacity?

This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material . Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance .

What measurements are used to determine specific heat?

Specific heat capacity (specific heat) (Cp) is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius. The value of the specific heat of water is 4.184 J/g⋅oC (the unit is read as Joules per gram per degree Celsius).

Which material has highest specific heat?

Liquid water has one of the highest specific heat capacities among common substances, about 4184 J⋅kg−1⋅K−1 at 20 °C; but that of ice, just below 0 °C, is only 2093 J⋅kg−1⋅K−1.

How can we determine the specific heat capacity of liquid?

To determine the specific heat capacity of another liquid, you could pour a measured mass of the hot liquid into the calorimeter (whose heat capacity is now known), and measure the fall in temperature of the liquid and the rise in temperature of the calorimeter, and hence deduce the specific heat capacity of the liquid …

How does salt concentration affect specific heat capacity of water experiment?

So, the greater is the concentration of the sodium chloride dissolved in the water, the lower will be the specific heat capacity of the water. In other words increasing the concentration of salt in water decreases the specific heat capacity of water.

How is calorimeter used in experiment?

A calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction occurs in solution in a calorimeter, the heat produced by the reaction is absorbed by the solution, which increases its temperature.

What is specific heat experiment?

I. INTRODUCTION. The objective of this experiment is to measure the specific heat of several different substances. This will be done by mixing two different substances and measuring their initial temperatures and then measuring their final temperature as they come to thermal equilibrium.
