If the temperature inside a room is 25°C and the temperature outside is ?10°C: a. What is the maximum relative humidity that can be accommodated inside the room before the window fogs over? (Assume the inside of the window is not insulated from the outside temperature). b. If it is a double-pane window such that the inside of the window is perfectly insulated from the outside, what will the maximum relative humidity be?

How many ways can you see that heat can transfer from the inside to the outside of your room on a cold day? List at least three and describe in detail how heat moves through the different kinds of materials (glass, brick, wood, insulation, etc.)—by conduction, convection or radiation. Which process do you suppose dominates?

10. Consider Cell B, which is a normal neuron (i.e. one with standard extra- and intracellular concentrations of most ion species). a) Plot membrane potential vs time for the postsynaptic response of Cell B in response to an inhibitory neurotransmitter being released onto it by another cell, Cell A. Label and number axes. b) Explain how this could result by the neurotransmitter affecting EITHER an anion channel or a cation channel on Cell B. c) What would be the change...
