Homework Statement
Let 25.2 J of heat be added to a particular ideal gas. As a result, its volume changes from 46.0 to 101.2 cm3 while the pressure remains constant at 1.0 atm. By how much did the internal energy of the gas change?
19.6 J is the answer which i understand how to get the...
Homework Statement
A sealed, evacuated 3.11 liter container initially contains 0.87 liter of liquid helium. As the contents of the container come into thermal equilibrium with the surroundings, the liquid helium vaporizes and turns into gas. If the temperature of the laboratory is 24.8°C...
11x10^-6 is the coef I have tried what I think is everything and still no luck on the right answer. I am pretty sure I am setting it up right DeltaL = coef L DeltaT but can't seem to work it out to get the right coef for the rod
A rod is measured to be exactly 21.81 cm long using a steel ruler at a temperature of 21.5°C. Both the rod and the ruler are placed in an oven with a temperature of 345.0 °C where the rod now measures 21.93 cm using the same ruler. What is the coefficient of thermal expansion for the material of...
