1. What is the difference between temperature and heat?
The difference between temperature and heat is that temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the transfer of energy between two bodies due to a temperature difference. Temperature is a scalar quantity and is measured in units such as degrees Celsius or Kelvin, while heat is a form of energy and is measured in joules.
2. How is temperature measured in different temperature scales?
Temperature can be measured in different temperature scales. The most commonly used scales are Celsius (°C), Kelvin (K), and Fahrenheit (°F). In the Celsius scale, the freezing point of water is defined as 0°C and the boiling point of water is defined as 100°C. In the Kelvin scale, the lowest possible temperature, called absolute zero, is defined as 0 K. The Kelvin scale is often used in scientific calculations because it directly relates to the average kinetic energy of the particles in a substance. The Fahrenheit scale is mainly used in the United States.
3. What are the three laws of thermodynamics and what do they state?
The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed in an isolated system. It can only be converted from one form to another or transferred between objects.
The second law of thermodynamics states that the entropy of an isolated system tends to increase over time. Entropy is a measure of the disorder or randomness of a system. This law also states that heat will always flow spontaneously from a hotter object to a colder object.
The third law of thermodynamics states that as the temperature of a system approaches absolute zero, the entropy of the system approaches a minimum value. It is impossible to achieve absolute zero in any finite number of steps. This law has important implications for the behavior of matter at extremely low temperatures.
