    Adiabatic expansion of a balloon

    Homework Statement A flexible balloon contains 0.375 mol of hydrogen sulfide gas H2S. Initially the balloon of H2S has a volume of 6750 cm^3 and a temperature of 29.0 C. The H2S first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns...

    H2S gas expanding isobarically then adiabatically to initial temperature

    Ok, so the change in internal energy is equal to zero, and the total work done is just equal Q, the heat supplied. Now I just can't find the final volume in m^3

    H2S gas expanding isobarically then adiabatically to initial temperature

    So if the change in temperature is 302K, that's the change in internal energy?

    Heat Loss in a House: Estimating k_eff

    Homework Statement In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is T_in= 20degrees C and the temperature outside is T_out = 0degrees C. The walls and uppermost ceiling of a typical house are supported by 2 x 6-inch wooden beams...
