An object was left in a room of unknown surrounding temperature. The temperature of the object was summarized below with respect to the time t(in minutes), the object was initially observed. Predict and complete the information, determine the temperature in Celsius when t = 30minutes. When t = 0, the temperature of the object is 30 degrees Celsius When t = 10 minutes, the temperature of the object is 32 degrees Celsius, When t = 20 minutes, the temperature of the object is 33.6 degrees Celsius, When t = 30 minutes, the temperature of the object is unknown. Assume the system obeys newton’s law of cooling and the surrounding temperature of the room did not change.
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.
