A 3/16 in. thick acrylic testing box with dimensions of 10.0 in. x 10.0 in. is covered with an unknown 0.50 in, insulation material. Determine the thermal
conductivity for the insulating material if a 25.0 W bulb is used to heat the box. You may
assume the only heat loss from the box occurs through the 10 x 10 test area. The bulb
maintains the inside temperature at 10.0 °C higher than the outside temperature.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

In a chemical reaction at equilibrium, the rate of the forward reaction the rate of the reverse reaction. if the rate of the forward reaction more products are formed.

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?
