The rebels are fighting the imperials on the icy planet Hoth. Han Solo didn’t dress for the weather (this ain’t Tattooine bud!), and is frozen solid (1234 kg of ice, at -123˚C ). Fortunately for Han, an AT-AT walker shoots its blasters and misses its target but hits Han which vaporizes the ice and brings him to a piping 102˚C. How much heat was added to Han Solo to turn him from a frozen chunk into a ‘Luke-warm’ rebel?
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.
Based on a grade 11 physics student, answer the following question:
The rebels are fighting the imperials on the icy planet Hoth. Han Solo didn’t dress for the weather (this ain’t Tattooine bud!), and is frozen solid (1234 kg of ice, at -123˚C ). Fortunately for Han, an AT-AT walker shoots its blasters and misses its target but hits Han which vaporizes the ice and brings him to a piping 102˚C. How much heat was added to Han Solo to turn him from a frozen chunk into a ‘Luke-warm’ rebel?
