Questions & Step-by-Step Solutions
According to the third law of thermodynamics, what happens as the temperature approaches absolute zero?
Step 1: Understand what absolute zero is. Absolute zero is the lowest possible temperature, which is 0 Kelvin or -273.15 degrees Celsius.
Step 2: Learn about entropy. Entropy is a measure of disorder or randomness in a system.
Step 3: Know what a perfect crystal is. A perfect crystal is a solid where the atoms are arranged in a highly ordered structure.
Step 4: Read the third law of thermodynamics. It states that as the temperature of a perfect crystal approaches absolute zero, its entropy approaches zero.
Step 5: Conclude that at absolute zero, a perfect crystal would have no disorder, meaning it is in a perfectly ordered state.
Third Law of Thermodynamics – As temperature approaches absolute zero, the entropy of a perfect crystal approaches zero.
