An immersion heater can be wired in series to a joulemeter to measure the added heat to a material. Once a certain amount of energy (Eh) had been added the temperature change was recorded (Dt) Along with the mass the equation Eh=cmDt can be used to find out c which is the specific heat capacity.

To determine the specific heat capacity of a solid conclusion?
To determine the specific heat capacity of a solid, conduct an experiment where you measure the temperature change of a known mass of the solid when a known amount of heat is added or removed. By calculating the specific heat capacity using the formula Q = mcΔT (where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change), you can determine the specific heat capacity of the solid. Repeat the experiment multiple times to ensure accuracy and reliability in your conclusion.
How do you determine specific heat capacity of a liquid?
To determine the specific heat capacity of a liquid, you can use a calorimeter. By measuring the initial and final temperatures of the liquid when it absorbs a known quantity of heat, you can calculate the specific heat capacity using the formula Q = mcΔT, where Q is the heat absorbed, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the change in temperature.

What is the independent variable in the calorimeter and specific heat experiment?
The independent variable in a calorimeter and specific heat experiment is typically the type of material being tested. By changing the type of material used in the experiment, one can examine how the specific heat capacity of different materials affects the amount of heat absorbed or released during a reaction.
What are the various properties of a substance that determine its heat capacity?
The specific heat capacity, density, and mass of a substance are properties that determine its heat capacity. Specific heat capacity is the amount of heat required to raise the temperature of one unit mass of the substance by one degree Celsius. Density and mass affect how much heat the substance can store and how quickly it can absorb or release heat.
How do you determine the specific heat capacity of an object by method of cooling?
To determine the specific heat capacity of an object by the cooling method, you would first heat the object to a known temperature and then immerse it in a known volume of water at a lower temperature. By monitoring the temperature change of the water and the object over time, you can calculate the specific heat capacity of the object using the formula q = mcΔT.
