Metal Block Experiment Procedure

This section details the practical investigation of specific heat capacity of a metal block through a controlled experiment. The procedure demonstrates how to measure specific heat capacity in a laboratory setting.

Vocabulary: Immersion heater - An electrical device used to heat materials directly through thermal contact.

Example: The experimental setup requires:

  • 1kg metal block
  • Thermometer
  • Power supply
  • 60W immersion heater
  • Insulation materials
  • Oil for thermal contact

Highlight: The experimental procedure involves:

  1. Setting up the apparatus safely
  2. Inserting the heater and thermometer
  3. Adding oil for better thermal contact
  4. Insulating the block
  5. Recording temperature changes over 10 minutes
  6. Calculating the total temperature rise

Definition: The specific heat capacity practical demonstrates how thermal energy transfer affects temperature change in a controlled environment.

Understanding Thermal Energy and Specific Heat Capacity

This section introduces the fundamental concepts of energy changes in systems and specific heat capacity calculations. The mathematical relationship between thermal energy, mass, and temperature change is explained through the equation E = mcΔθ.

Definition: Specific heat capacity is the amount of thermal energy required to change the temperature of 1 kg of a material by 1°C.

Example: Different materials have varying specific heat capacities:

  • Air: 1005 J/kg°C
  • Water: 4200 J/kg°C
  • Aluminium: 900 J/kg°C
  • Concrete: 880 J/kg°C

Highlight: The equation E = mcΔθ is essential for calculating thermal energy changes, where:

  • E = change in thermal energy (Joules)
  • m = mass (kg)
  • c = specific heat capacity (J/kg°C)
  • Δθ = change in temperature (°C)
