How to Determine Specific Heat Capacity of Substance - Physics Experiment

The video tutorial explains the concept of specific heat capacity, focusing on the experiment to determine the specific heat capacity of aluminum. It covers the necessary equipment, assumptions, and detailed steps for conducting the experiment. The tutorial also explains how to calculate the specific heat capacity using the formula E = MCΔθ, and discusses the importance of insulation to minimize energy loss. Finally, it demonstrates the calculation process using experimental data.

What is the formula that relates energy, mass, specific heat capacity, and temperature change?

• E = MΔθ/C

• E = MCΔθ

• E = CΔθ/M

• E = M/CΔθ

What is the purpose of the electrical heater in the experiment?

• To measure the mass of the block

• To insulate the aluminum block

• To supply thermal energy to the block

• To measure the temperature of the block

Why is the aluminum block covered with insulating material?

• To increase the mass of the block

• To prevent the block from melting

• To make the block easier to handle

• To reduce energy loss to the surroundings

Why do we wait for the thermometer to reach its maximum value before taking the final temperature?

• To stabilize the initial temperature

• To cool down the block

• To allow residual thermal energy to be absorbed

• To ensure the heater is completely off

How is the energy supplied to the block calculated in this experiment?

• By dividing power by time

• By measuring the temperature change directly

• By using the mass and specific heat capacity

• By multiplying power and time
