A subsection of Physics, 9702, through 16. Thermodynamics
Listing 10 of 16 questions
State an expression, in terms of work done and heating, that is used to calculate the increase in internal energy of a system. State and explain, in terms of your expression in , the change, if any, in the internal energy of the water in an ice cube when the ice melts, at atmospheric pressure, to form a liquid without any change of temperature, of the gas in a tyre when the tyre bursts so that the gas suddenly increases in volume. Assume that the gas is ideal.
