Heat Energy and Temperature Calculations

The video tutorial explains how to calculate the heat energy required to raise the temperature of oil from 23°C to 191°C. It introduces the equation Q = MCΔT, where Q is the heat in joules, M is the mass in grams, and ΔT is the temperature change. The tutorial covers converting mass from kilograms to grams, calculating the temperature change, and performing the final calculation to find the heat energy in joules and kogs.
