Calculating Specific Heat Through Metal and Water Interaction

The video tutorial demonstrates a specific heat lab experiment to find the specific heat of two metal samples using a simple calorimeter. The process involves heating metal samples in boiling water, transferring them to a calorimeter with room temperature water, and measuring the temperature change. The specific heat of the metals is calculated using the heat absorbed by the water, assuming no heat loss to the environment. The experiment is conducted for two metal samples, A and B, with different masses and specific heats.

What is the equation used to calculate the specific heat of a substance?

• Q = specific heat / mass x delta T

• Q = mass / specific heat x delta T

• Q = mass x specific heat x delta T

• Q = delta T / mass x specific heat

What is the purpose of using a calorimeter in this experiment?

What assumption is made about the energy transfer in the calorimeter?

• All energy given off by the metal is absorbed by the water

• No energy is transferred

• All energy is lost to the surroundings

• Energy is only partially absorbed by the water
