1. What are the temperatures for freezing water on the Celsius and Fahrenheit scales? For boiling water? The Celsius scale for freezing temperature of water is 0oC and boiling point is 100oC. The Fahrenheit scale for freezing temperature of water is 32oF and boiling point is 212oF. 2. Distinguish between temperature and heat. Objects do not possess heat. When two objects interact with different temperatures, there’s transfer of energy between objects is called heat. For example, a hot iron rod dipped in tepid water. There will be a decrease in the iron’s temperature, consequently losing energy. On the other hand, there will be an increase in the water’s temperature hence gaining energy. The measure of the translational …show more content…
For instance, two metal bars of the same mass but of different composition are heated simultaneously. The metal A’s temperature rises faster than metal B; therefore we conclude that metal A possesses a lower specific heat. It is in the swift increase in temperature that we consider objects to have low specific heat, in this case metal A. 4. Which has a greater amount of internal energy—an iceberg or a cup of hot coffee. Defend your answer. The internal energy of an object is the total energy it contains due to it molecular motion and interaction. The molecules in a cup of coffee, in liquid state, will have copious energy than those in the iceberg, in solid state; there is greater internal energy in the cup of coffee than the iceberg. On the other hand, the iceberg is composed of much larger quantity of molecules than the cup of coffee. Therefore the total internal energy of the iceberg is larger than the total energy of the cup of coffee. 5. Why does the pressure of a gas enclosed in a rigid container increase as the temperature
