Your calibrated soup container has served you pretty well over the last several weeks, so you have decided to use it to heat up your soup for lunch using the microwave oven located just outside your lab. The oven warms food by delivering electromagnetic radiation with a frequency of 2.45 GHz at a rate of 7.39 x 10^26 photons per second. Your soup has a mass of 524 grams and your calibrated container has a heat capacity of 69.9 J °C-1. If the initial temperature of your soup is 25 °C, what will be its temperature if you allow it to heat in the microwave for 1.5 minutes? [Assume that the specific heat capacity of your soup is 4.18 J g-1 °C-1.]

Techniques and applications of quantum theory

Quantum theory, often known as quantum physics, is the foundation of modern physics and encompasses the nature and behavior of matter and energy at the atomic and molecular levels. As the exact nature and behavior of atomic and subatomic particles are impossible to determine, the laws of classical physics do not apply to this discipline. As a result, quantum field theory is primarily based on assumptions and probabilities.
