How do you measure specific heat capacity?

To measure specific heat capacity, use the equation Q = mcΔT and a calorimeter to determine the amount of heat absorbed.

Specific heat capacity is the amount of heat energy required to raise the temperature of one kilogram of a substance by one degree Celsius. It is measured in joules per kilogram per degree Celsius (J/kg°C). To measure specific heat capacity, a calorimeter is used to determine the amount of heat absorbed by a substance when its temperature is raised.

The equation Q = mcΔT is used to calculate the amount of heat absorbed by a substance. Q is the amount of heat energy absorbed, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature of the substance.

To measure specific heat capacity, a known mass of the substance is heated and then placed in a calorimeter filled with a known mass of water. The initial and final temperatures of the water are measured, and the amount of heat absorbed by the water is calculated using the equation Q = mcΔT. The amount of heat absorbed by the substance is then calculated by subtracting the heat absorbed by the water from the total heat supplied.

By measuring the mass of the substance, the mass of the water, and the change in temperature of the water, the specific heat capacity of the substance can be calculated using the equation c = Q/(mΔT). This method can be used to measure the specific heat capacity of solids, liquids, and gases.
