The video tutorial explains the concept of specific heat, which is the amount of heat required to raise the temperature of a unit mass by one unit. It introduces the formula for specific heat and its units, including calorie per gram degree Celsius and joule per kilogram Kelvin. The tutorial provides an example calculation to determine the heat needed to raise the temperature of 450 grams of water from 25°C to 100°C, resulting in 33,750 calories. The video concludes by highlighting the importance of specific heat in daily life and hints at further exploration in the next lesson.
