Virtual Specific Heat Capacity Lab & Calorimetry Experiment

MISSION: THERMAL ENERGY TRANSFER

[●] SYSTEMS: ONLINE

Welcome to the Senpai Corner specific heat capacity lab. This interactive simulation allows students to conduct a virtual calorimetry experiment to see how different materials respond to thermal energy. By heating substances like Iron, Copper, Brick, and Glass with a constant power source, you can calculate the specific heat constant ($c$) and observe the relationship between mass, time, and temperature change (ΔT).

LEARNING OBJECTIVES

Identify how different materials (iron, copper, brick and glass) absorb heat at different rates.
Calculate total heat energy (Q) using the formula: Q = P × t.
Analyze real-time "Temperature vs. Time" graphs to determine the specific heat capacity (c) of known samples.
Understand higher heat capacity materials require more energy to change temperature than lower heat capacity materials.

THE THEORY BEHIND THE SPECIFIC HEAT EXPERIMENT

Specific heat capacity is the amount of energy needed to raise the temperature of 1 kilogram of a substance by 1°C (or 1 Kelvin). In this lab, we use a constant heating power of 500 Watts applied to a 1.0 kg mass.
The fundamental equation for heat transfer is: Q = mcΔT
Where:
Q = Total heat energy (measured in Joules)
m = Mass of the object (1.0 kg in this lab)
c = Specific heat capacity constant (J/kg·K)
ΔT = Change in temperature (Final Temp - Initial Temp)
Because we are using a timed heater, we also calculate energy using: Q = Power × Time (Q = P × t)

FAQ

Q: Why does Copper heat up faster than Glass?

A: Copper has a lower specific heat capacity (385 J/kg·K) than Glass (840 J/kg·K). This means Copper requires less energy to increase its temperature by 1°C.

Q: What is the significance of the graph's slope?

A: The slope of the line represents the rate of temperature change. A steeper slope indicates a material that heats up quickly due to a low specific heat capacity.
