Heat Transfer and Specific Heat

The video tutorial explains how to calculate the specific heat of a metal using a heat transfer experiment. A piece of metal is transferred from boiling water to cooler water, and the change in temperature is used to determine the specific heat. The tutorial breaks down the problem into two parts: analyzing the heat absorbed by the water and the heat released by the metal. By applying the formula q = c * m * ΔT, the specific heat of the metal is calculated, demonstrating the conservation of energy principle.

What is the initial temperature of the water before the metal is added?

• 22 degrees Celsius

• 28.5 degrees Celsius

• 100 degrees Celsius

• 0 degrees Celsius

Which equation is used to calculate the heat absorbed by the water?

• q = m * c * delta T

• q = m * v * delta T

• q = m * c * v

• q = c * v * delta T

What is the specific heat of water used in the calculation?

• 1.0 J/g°C

• 2.5 J/g°C
