    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...

    Solving Flexible Balloon H2S Gas Problem: Q, ΔU, W & V

    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

    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...
