show all calculations with formula 1. A 250.0 ml pyrex beaker is filled to the brim with water at 30. Celsius; then it was heated to 95 Celsius. Find the amount of water (ml) that will overflow. 2. A steel bar has the desired length when at 30. Celisius. How much stress (N/m^2) is needed to keep it at this length if the temperature increases to 50. Celsius.
Kinetic Theory of Gas
The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all directions. It also says that the constituent particles/molecules undergo elastic collision, which means that the total kinetic energy remains constant before and after the collision. The average kinetic energy of the particles also determines the pressure of the gas.
P-V Diagram
A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and volume (V) corresponding to the thermodynamic system under study. The P-V diagram is used as an indicator diagram to control the given thermodynamic system.
