#4 A wood box [k = 0.16 W/(m degree C) ] is kept at a constant temperature of 20 degrees C by an electric heater. The box is 0.4 x 0.4 x 0.4 m, and its walls
are 2.5 cm thick. If the temperature outside the box is 4 degrees C, how much
power will the heater use? (Include the base of the box in the area.)
(W=?) I need to solve for w

Scout feels ill one day before school. her mother puts a thermometer in her mouth and the temperature begins to climb to 100°f. what is happening between the cooler thermometer and scout's body? a) scout's body is applying a force to the particles in the thermometer. b) kinetic energy is being transferred from her mouth to the thermometer. c) potential energy is being lost by the thermometer and gained by scout's body. d) the potential energy stored in foods is converted to mechanical energy to raise the mercury in the thermometer.

Which planet do you think would be easiest for humans to colonize some day?

Which sections of the heating curve illustrate this process?
