A rectangular glass window pane on a house has a width of 1.5 m, a height of 2.15 m, and a thickness of 0.55 cm. Find the energy transferred through the window by conduction in 12 hours on a day when the inside temperature of the house is 24°C and the outside temperature is 2.5°C. Take surface air layers into consideration

How much energy must be transferred as heat for a reversible isothermal expansion of an ideal gas at 132 degrees Celcius if the enthropy of the gas increases by 46.0 J/K

For bacteriological testing of water supplies and in medical clinics, samples must routinely be incubated for 24 h at 37°C. A standard constant - temperature bath with electric heating and thermostatic control is not suitable in developing nations without continuously operating electric power lines. Peace Corps volunteer and MIT engineer Amy Smith invented a low - cost, low-maintenance incubator to fill the need. The device consists of a foam-insulated box containing several packets of a waxy material that melts at 37.0°C, interspersed among tubes, dishes, or bottles containing the test samples and growth medium (food for bacteria). Outside the box, the waxy material is first melted by a stove or solar energy collector. Then it is put into the box to keep the test samples warm as it solidifies. The heat of fusion of the phase-change material is 205 kJ/kg. Model the insulation as a panel with surface area 0.490 m2, thickness 9.50 cm, and conductivity 0.012 0 W/m ∙ °C. Assume the…

A rectangular glass window pane on a house has a width of 1.1 m, a height of 2.1 m, and a thickness of 0.48 cm. Find the energy transferred through the window by conduction in 12 hours on a day when the inside temperature of the house is 22°C and the outside temperature is 2.0°C. Take surface air layers into consideration.
