An electronics device generates 33.4 W of heat energy during normal operation. The heat is dissipated from the top surface of the device to ambient air at 21°C. If the top surface area is 0.176 m2 and the convection heat transfer coefficient is 7.019 W/m2· K, what will be the surface temperature (in °C) of the device [round your final answer to one decimal place]?
Either give an exact answer, or make sure you include at least 4 significant digits on your answer.
The pressure P (in kilopascals), volume V (in liters), and temperature T (in kelvins) of a mole of an
ideal gas are related by the equation PV = 8.31T. Find the rate at which the volume is changing
when the temperature is 330 K and increasing at a rate of 0.15 K/s and the pressure is 26 and
increasing at a rate of 0.03 kPa/s.

Problem 1.42. The specific heat capacity of Albertson's Rotini Tricolore is ap-
proximately 1.8 J/g °C. Suppose you toss 340 g of this pasta (at 25°C) into 1.5
liters of boiling water. What effect does this have on the temperature of the water
(before there is time for the stove to provide more heat)?
