Specific Heat Capacity Concepts

The video tutorial explains how to measure the specific heat capacity of a metal using an experimental method. It involves heating the metal to a known temperature, transferring it to cold water, and using the change in temperature to calculate the specific heat capacity. The tutorial includes an example problem with a 250g block of aluminium, demonstrating the calculation process. The video concludes with a summary and encourages viewers to engage with the content.

What is the first step in measuring the specific heat capacity of a metal?

• Place the metal in cold water

• Measure the initial temperature of the water

• Heat the metal to a known temperature

• Weigh the metal

Why is a polystyrene cup used in the experiment?

• It is easy to clean
