How do you find the specific heat capacity of a lab?
Often applied to metallic elements, specific heat can be used as a basis for comparing how different substances absorb and transfer energy. To measure specific heat in the laboratory, a calorimeter of some kind must be used. A calorimeter is a well-insulated container that can measure energy changes.

How do you find the heat capacity of a calorimeter?
From the amount of water in the calorimeter and the temperature change undergone by the water, the quantity of heat absorbed by the calorimeter, qcal, can be determined. The heat capacity of the calorimeter, Ccal, is determined by dividing qcal by the temperature change.
What is the heat capacity of zinc?

What is C in heat capacity?
An object’s heat capacity (symbol C) is defined as the ratio of the amount of heat energy transferred to an object to the resulting increase in temperature of the object. C=QΔT. C = Q Δ T .
What is Q in heat capacity?
Q = m•C•ΔT where Q is the quantity of heat transferred to or from the object, m is the mass of the object, C is the specific heat capacity of the material the object is composed of, and ΔT is the resulting temperature change of the object.

What is the specific heat of lead?
By allowing lead shot to fall inside a closed pipe, we determined the specific heat of lead to be 833J/kgK. This compared very poorly with the theoretical value of 157J/kgK. Introduction. One of the most fundamental physical properties is the relation between mechanical energy and heat.
What is the specific heat capacity of metal?

What is the specific heat capacity of 1g of water?
s∆T (9.1) In this equation, the proportionality constant C. s. is called the specific heat capacity and every substance has a characteristic value. For example, the specific heat capacity of water is 4.184 J g−1 ◦C−1. This value means that 4.184 J of heat is required to raise the temperature of 1 g of water by 1 ◦C.
