A 28-m3 tank is filled with 2910 moles of an ideal gas. The temperature of the gas is initially 302 K, but it is raised to 740 K.
1) What is the change in the pressure of the gas inside the tank?
2) Let's assume that the tank is made out of a material which has a coefficient of linear expansion of 6.5 × 10-5 K-1, and that the temperature of the tank is always the same as the temperature of the gas. Remember that the space inside the tank will expand as if it were made of the material surrounding it. What is the change in the volume of the tank due to the increase in temperature from 302 K to 740 K?
3) Given that the tank expands a bit, what is the actual change in the gas pressure due to the increase in temperature?
The nonconservative wind and lift forces take the balloon up, doing +9.70 104 J of work on the balloon in the process. Evaluate at what height above the surface of the earth does the balloon have a speed of 7.00 m/s? Enter a number.
implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves).
