First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.

Answer the last three items (8 to 10)
When water boils in a pot with a loose lid, the increasedpressure forces the lid upward, releasing steam and reducing the pressurein the pot so that the lid drops back down. If the water continues toboil, the lid can rattle upward and downward. Consider a 1 L pot halffilled with boiling water. In this case there is half a liter, or 1/11.2 mol, ofair and steam above the water When the water is rapidly boiling, estimate the height to which the lid jumps during a steam-release event.
